43. Pornography Classification: The Hidden Clues in Video Space-Time Daniel Moreira and Sandra Avila and Mauricio Perez and Daniel Moraes and Vanessa Testoni and Eduardo Valle and Siome Goldenstein and Anderson Rocha In Press: Forensic Science International 2016 Show/Hide Abstract.

Abstract: As web technologies and social networks become part of the general public's life, the problem of automatically detecting pornography is into every parent's mind — nobody feels completely safe when their children go online. In this paper, we focus on video-pornography classification, a hard problem in which traditional methods often employ still-image techniques — labeling frames individually prior to a global decision. Frame-based approaches, however, ignore significant cogent information brought by motion. Here, we introduce a space-temporal interest point detector and descriptor called Temporal Robust Features (TRoF). TRoF was custom-tailored for efficient (low processing time and memory footprint) and effective (high classification accuracy and low false negative rate) motion description, particularly suited to the task at hand. We aggregate local information extracted by TRoF into a mid-level representation using Fisher Vectors, the state-of-the-art model of Bags of Visual Words (BoVW). We evaluate our original strategy, contrasting it both to commercial pornography detection solutions, and to BoVW solutions based upon other space-temporal features from the scientific literature. The performance is assessed using the Pornography-2k dataset, a new challenging pornographic benchmark, comprising 2,000 web videos and 140 hours of video footage. The dataset is also a contribution of this work and is very assorted, including both professional and amateur content, and it depicts several genres of pornography, from cartoon to live action, with diverse behavior and ethnicity. The best approach, based on a dense application of TRoF, yields a classification error reduction of almost 79\% when compared to the best commercial classifier. A sparse description relying on TRoF detector is also noteworthy, for yielding a classification error reduction of over 69\%, with 19$\times$ less memory footprint than the dense solution, and yet can also be implemented to meet real-time requirements.

36. Multiple Parenting Phylogeny Relationships in Digital Images A. Oliveira and P. Ferrara and A. De Rosa and A. Piva and M. Barni and S. Goldenstein and Z. Dias and A. Rocha IEEE Transactions on Information Forensics and Security ISSN: 1556–6013, Vol. 11, Num. 2, pgs. 328–343, 2016 doi:10.1109/TIFS.2015.2493989 PDF. Show/Hide Abstract.

Abstract: Recently, several studies have been concerned with modeling the parenthood relationships between near duplicates in a set of images. Two images share a parenthood relationship if one is obtained by applying transformations to the other. However, this is not the only form of parenting that can exist among images. An image might be a composition created through the combination of the semantic information existent in two or more source images, establishing a relationship between the sources and the composite. The problem of identifying these relations in a set containing near-duplicate subsets of source and composition images is referred to as multiple parenting phylogeny. Thus far, researchers tackled this problem with a three-step solution:1) separation of near-duplicate groups; 2) classification of the relations between the groups; and 3) identification of the images used to create the original composition. In this work, we extend upon this framework by introducing key improvements, such as better identification of when two images share content, and improved ways to compare this content. In addition, we also introduce a new realistic professionally created data set of compositions involving multiple parenting relationships. The method we present in this paper is properly evaluated through quantitative metrics, established for assessing the accuracy in finding multiple parenting relationships. Finally, we discuss some particularities of the framework, such as the importance of an accurate reconstruction of phylogenies and the method’s behavior when dealing with more complex compositions.

35. Manifold Learning and Spectral Clustering for Image Phylogeny Forests Marina Oikawa and Zanoni Dias and Anderson Rocha and Siome Goldenstein IEEE Transactions on Information Forensics and Security ISSN: 1556–6013, Vol. 11, Num. 1, pgs. 5-18, 2016 doi:10.1109/TIFS.2015.2442527 PDF. Show/Hide Abstract.

Abstract: The ever-increasing number of gadgets being used to create digital content, as well as the easiness in sharing, editing, and republishing this content, brings the problem of dealing with a large amount of digital objects (e.g., images or videos) whose content is very similar. Some issues faced by investigators of digital crimes when analyzing this type of data include finding the original source of a suspect image, and the responsible for first publishing it. It is also challenging to determine how these objects are related to each other. Recent efforts in developing algorithms to find automatically the underlying relationship among groups of digital media objects with similar content have been explored in the multimedia phylogeny field. A tree structure is used to represent the relationship among these objects, inspired by the phylogenetic trees in biology. Discovering whether these objects came from the same source or from different sources is fundamentally a clustering problem: 1) related objects belong to the same cluster (tree) and 2) unrelated objects should fit in different clusters. In this paper, we address the problem of finding these clusters in sets of semantically similar images, prior to tree reconstruction. We propose the combination of manifold learning and spectral clustering approaches, which have been successfully used in different applications embedding the original data into a lower, but meaningful, dimensional space. Experiments with more than 40 000 test cases show that the proposed approach improves the accuracy in finding the correct number of trees in the set, as well as the reconstruction of the phylogeny trees

Automated Multi-Lesion Detection for Referable Diabetic Retinopathy in Indigenous Health Care Ramon Pires and Tiago Carvalho and Geoffrey Spurling and Siome Goldenstein and Jacques Wainer and Alan Luckie and Herbert Jelinek and Anderson Rocha Plos One ISSN: 1932-6203, 2015 doi:10.1371/journal.pone.0127664 PDF.

Abstract: Diabetic Retinopathy (DR) is a complication of diabetes mellitus that affects more than one-quarter of the population with diabetes, and can lead to blindness if not discovered in time. An automated screening enables the identification of patients who need further medical attention. This study aimed to classify retinal images of Aboriginal and Torres Strait Islander peoples utilizing an automated computer-based multi-lesion eye screening program for dia- betic retinopathy. The multi-lesion classifier was trained on 1,014 images from the São Paulo Eye Hospital and tested on retinal images containing no DR-related lesion, single lesions, or multiple types of lesions from the Inala Aboriginal and Torres Strait Islander health care centre. The automated multi-lesion classifier has the potential to enhance the efficiency of clinical practice delivering diabetic retinopathy screening. Our program does not necessitate image samples for training from any specific ethnic group or population being assessed and is independent of image pre- or post-processing to identify retinal lesions. In this Aboriginal and Torres Strait Islander population, the program achieved 100\% sensitivity and 88.9\% specificity in identifying bright lesions, while detection of red lesions achieved a sensitivity of 67\% and specificity of 95\%. When both bright and red lesions were present, 100\% sensitivity with 88.9\% specificity was obtained. All results obtained with this automated screening program meet WHO standards for diabetic retinopathy screening.

32. Image Phylogeny Forests Reconstruction Filipe Costa and Marina Oikawa and Zanoni Dias and Siome Goldenstein and Anderson Rocha IEEE Transactions on Information Forensics and Security ISSN: 1556–6013, Vol. 9, Num. 10, pgs. 1533–1546, 2014 doi:10.1109/TIFS.2014.2340017 PDF. Show/Hide Abstract.

Abstract: Today, a simple search for an image on the Web can return thousands of related images. Some results are exact copies, some are variants (or near-duplicates) of the same digital image, and others are unrelated. Although we can recognize some of these images as being semantically similar, it is not as straightforward to find which image is the original. It is not easy either to find the chain of transformations used to create each modified version. There are several approaches in the literature to identify near-duplicate images, as well as to reconstruct their relational structure. For the latter, a common representation uses the parent–child relationship, allowing us to visualize the evolution of modifications as a phylogeny tree. However, most of the approaches are restricted to the case of finding the tree of evolution of the near-duplicates, with few works dealing with sets of trees. Since one set of near-duplicates can contain n independent subsets, it is necessary to reconstruct not only one phylogeny tree, but several trees that will compose a phylogeny forest. In this paper, through the analysis of the state-of-the- art image phylogeny algorithms, we introduce a novel approach to deal with phylogeny forests, based on different combinations of these algorithms, aiming at improving their reconstruction accuracy. We analyze the effectiveness of each combination and evaluate our method with more than 40 000 testing cases, using quantitative metrics.

Abstract: Recently, there has been a lot of success in the development of effective binary classifiers. Although many statistical classification techniques have natural multiclass extensions, some, such as the support vector machines, do not. The existing techniques for mapping multiclass problems onto a set of simpler binary classification problems run into serious efficiency problems when there are hundreds or even thousands of classes, and these are the scenarios where this paper’s contributions shine. We introduce the concept of correlation and joint probability of base binary learners. We learn these properties during the training stage, group the binary leaner’s based on their independence and, with a Bayesian approach, combine the results to predict the class of a new instance. Finally, we also discuss two additional strategies: one to reduce the number of required base learners in the multiclass classification, and another to find new base learners that might best complement the existing set. We use these two new procedures iteratively to complement the initial solution and improve the overall performance. This paper has two goals: finding the most discriminative binary classifiers to solve a multiclass problem and keeping up the efficiency, i.e., small number of base learners. We validate and compare the method with a diverse set of methods of the literature in several public available datasets that range from small (10 to 26 classes) to large multiclass problems (1000 classes) always using simple reproducible scenarios.

Assessing the Need for Referral in Automatic Diabetic Retinopathy Detection Ramon Pires and Herbert Jelinek and Jacques Wainer and Siome Goldenstein and Eduardo Valle and Anderson Rocha IEEE Transactions on Biomededical Engineering ISSN: 0018-9294, Vol. 60, Num. 12, pgs. 3391–3398, 2013 doi:10.1109/TBME.2013.2278845 PDF.

Abstract: Emerging technologies in health care aim at reducing unnecessary visits to medical specialists, minimizing overall cost of treatment and optimizing the number of patients seen by each doctor. This paper explores image recognition for the screening of diabetic retinopathy, a complication of diabetes that can lead to blindness if not discovered in its initial stages. Many previous reports on DR imaging focus on the segmentation of the retinal image, on quality assessment, and on the analysis of presence of DR-related lesions. Although this study has advanced the detection of individual DR lesions from retinal images, the simple presence of any lesion is not enough to decide on the need for referral of a patient. Deciding if a patient should be referred to a doctor is an es- sential requirement for the deployment of an automated screening tool for rural and remote communities. We introduce an algorithm to make that decision based on the fusion of results by metaclassifi- cation. The input of the metaclassifier is the output of several lesion detectors, creating a powerful high-level feature representation for the retinal images. We explore alternatives for the bag-of-visual- words (BoVW)-based lesion detectors, which critically depends on the choices of coding and pooling the low-level local descriptors. The final classification approach achieved an area under the curve of 93.4\% using SOFT–MAX BoVW (soft-assignment coding/max pooling), without the need of normalizing the high-level feature vector of scores.

Abstract: In this paper, we present an algorithm to detect the presence of diabetic retinopathy (DR)-related lesions from fundus images based on a common analytical approach that is capable of identifying both red and bright lesions without requiring specific pre- or postprocessing. Our solution constructs a visual word dictionary representing points of interest (PoIs) located within regions marked by specialists that contain lesions associated with DR and classifies the fundus images based on the presence or absence of these PoIs as normal or DR-related pathology. The novelty of our approach is in locating DR lesions in the optic fundus images using visual words that combines feature information contained within the images in a framework easily extendible to different types of retinal lesions or pathologies and builds a specific projection space for each class of interest (e.g., white lesions such as exudates or normal regions) instead of a common dictionary for all classes. The visual words dictionary was applied to classifying bright and red lesions with classical cross validation and cross dataset validation to indicate the robustness of this approach. We obtained an area under the curve (AUC) of 95.3\% for white lesion detection and an AUC of 93.3\% for red lesion detection using fivefold cross validation and our own data consisting of 687 images of normal retinae, 245 images with bright lesions, 191 with red lesions, and 109 with signs of both bright and red lesions. For cross dataset analysis, the visual dictionary also achieves compelling results using our images as the training set and the RetiDB and Messidor images as test sets. In this case, the image classification resulted in an AUC of 88.1\% when classifying the RetiDB dataset and in an AUC of 89.3\% when classifying the Messidor dataset, both cases for bright lesion detection. The results indicate the potential for training with different acquisition images under different setup conditions with a high accuracy of - eferral based on the presence of either red or bright lesions or both. The robustness of the visual dictionary against image quality (blurring), resolution, and retinal background, makes it a strong candidate for DR screening of large, diverse communities with varying cameras and settings and levels of expertise for image capture.

Abstract: Nowadays, digital content is widespread and also easily redistributable, either lawfully or unlawfully. Images and other digital content can also mutate as they spread out. For example, after images are posted on the Internet, other users can copy, resize and/or re-encode them and then repost their versions, thereby generating similar but not identical copies. While it is straightforward to detect exact image duplicates, this is not the case for slightly modified versions. In the last decade, some researchers have successfully focused on the design and deployment of near-duplicate detection and recognition systems to identify the cohabiting versions of a given document in the wild. Those efforts notwithstanding, only recently have there been the first attempts to go beyond the detection of near-duplicates to find the structure of evolution within a set of images. In this paper, we tackle and formally define the problem of identifying these image relationships within a set of near-duplicate images, what we call Image Phylogeny Tree (IPT), due to its natural analogy with biological systems. The mechanism of building IPTs aims at finding the structure of transformations and their parameters if necessary, among a near-duplicate image set, and has immediate applications in security and law-enforcement, forensics, copyright enforcement, and news tracking services. We devise a method for calculating an asymmetric dissimilarity matrix from a set of near-duplicate images and formally introduce an efficient algorithm to build IPTs from such a matrix. We validate our approach with more than 625000 test cases, including both synthetic and real data, and show that when using an appropriate dissimilarity function we can obtain good IPT reconstruction even when some pieces of information are missing. We also evaluate our solution when there are more than one near-duplicate sets in the pool of analysis and compare to other recent related approaches in the literature.

Abstract: Digital images are everywhere—from our cell phones to the pages of our online news sites. How we choose to use digital image processing raises a surprising host of legal and ethical questions that we must address. What are the ramifications of hiding data within an innocent image? Is this an intentional security practice when used legitimately, or intentional deception? Is tampering with an image appropriate in cases where the image might affect public behavior? Does an image represent a crime, or is it simply a representation of a scene that has never existed? Before action can even be taken on the basis of a questionable image, we must detect something about the image itself. Investigators from a diverse set of fields require the best possible tools to tackle the challenges presented by the malicious use of today's digital image processing techniques. In this survey, we introduce the emerging field of digital image forensics, including the main topic areas of source camera identification, forgery detection, and steganalysis. In source camera identification, we seek to identify the particular model of a camera, or the exact camera, that produced an image. Forgery detection's goal is to establish the authenticity of an image, or to expose any potential tampering the image might have undergone. With steganalysis, the detection of hidden data within an image is performed, with a possible attempt to recover any detected data. Each of these components of digital image forensics is described in detail, along with a critical analysis of the state of the art, and recommendations for the direction of future research.

Abstract: Contemporary Vision and Pattern Recognition problems such as face recognition, fingerprinting identification, image categorization, and DNA sequencing often have an arbitrarily large number of classes and properties to consider. To deal with such complex problems using just one feature descriptor is a difficult task and feature fusion may become mandatory. Although normal feature fusion is quite effective for some problems, it can yield unexpected classification results when the different features are not properly normalized and preprocessed. Besides it has the drawback of increasing the dimensionality which might require more training data. To cope with these problems, this paper introduces a unified approach that can combine many features and classifiers that requires less training and is more adequate to some problems than a naïve method, where all features are simply concatenated and fed independently to each classification algorithm. Besides that, the presented technique is amenable to continuous learning, both when refining a learned model and also when adding new classes to be discriminated. The introduced fusion approach is validated using a multi-class fruit-and-vegetable categorization task in a semi-controlled environment, such as a distribution center or the supermarket cashier. The results show that the solution is able to reduce the classification error in up to 15 percentage points with respect to the baseline.

Abstract: Application of computer vision to track changes in human facial expressions during long-duration spaceflight may be a useful way to unobtrusively detect the presence of stress during critical operations. To develop such an approach, we applied optical computer recognition (OCR) algorithms for detecting facial changes during performance while people experienced both low- and high-stressor performance demands. Workload and social feedback were used to vary performance stress in 60 healthy adults (29 men, 31 women; mean age 30 yr). High-stressor scenarios involved more difficult performance tasks, negative social feedback, and greater time pressure relative to low workload scenarios. Stress reactions were tracked using self-report ratings, salivary cortisol, and heart rate. Subjects also completed personality, mood, and alexi- thymia questionnaires. To bootstrap development of the OCR algorithm, we had a human observer, blind to stressor condition, identify the expressive elements of the face of people undergoing high- vs. low- stressor performance. Different sets of videos of subjects’ faces during performance conditions were used for OCR algorithm training. Subjec- tive ratings of stress, task difficulty, effort required, frustration, and negative mood were significantly increased during high-stressor perfor- mance bouts relative to low-stressor bouts (all p < 0.01). The OCR algorithm was refined to provide robust 3-d tracking of facial expres- sions during head movement. Movements of eyebrows and asymmetries in the mouth were extracted. These parameters are being used in a Hidden Markov model to identify high- and low-stressor conditions. Preliminary results suggest that an OCR algorithm using mouth and eyebrow regions has the potential to discriminate high- from low- stressor performance bouts in 75–88\% of subjects. The validity of the workload paradigm to induce differential levels of stress in facial ex- pressions was established. The paradigm also provided the basic stress- related facial expressions required to establish a prototypical OCR al- gorithm to detect such changes. Efforts are underway to further improve the OCR algorithm by adding facial touching and automating applica- tion of the deformable masks and OCR algorithms to video footage of the moving faces as a prelude to blind validation of the automated ap- proach.

Abstract: Predictive filters are essential tools in modern science. They perform state prediction and parameter estimation in fields such as robotics, computer vi- sion, and computer graphics. Sometimes also called Bayesian filters, they apply the Bayesian rule of conditional probability to combine a predicted behavior with some corrupted indirect observation. When we study and solve a problem, we first need its proper mathematical formula- tion. Finding the essential parameters that best describe the system is hard; modeling their behaviors over time is even more challenging. Usually, we also have an inspec- tion mechanism that provides us with indirect measurements, the observations, of the hidden underlying parameters. We also need to deal with the concept of uncertainty, and use random variables to represent both the state and the observations. Predictive filters are a family of estimation techniques. They combine the uncertain prediction from the system’s dynamics and the corrupted observation. There are many different predictive filters, each dealing with different types of mathematical represen- tations for random variables and system dynamics. Here, the reader will find a dense introduction to predictive filters. After a general introduction, we discuss briefly discussion about mathematical modeling of systems: state representation, dynamics, and observation. Then, we expose some basic issues related to random variables and uncertainty modeling, and discuss four implemen- tations of predictive filters, in order of complexity: the Kalman filter, the extended Kalman filter, the particle filter, and the unscented Kalman filter.

Abstract: Deformable models are a useful modeling paradigm in computer vision. A deformable model is a curve, a surface, or a volume, whose shape, position, and orientation are controlled through a set of parameters. They can represent manufactured objects, human faces and skeletons, and even bodies of fluid. With low-level computer vision and image processing techniques, such as optical flow, we extract relevant information from images. Then, we use this information to change the parameters of the model iteratively until we find a good approximation of the object in the images. When we have multiple computer vision algorithms providing distinct sources of information (cues), we have to deal with the difficult problem of combining these, sometimes conflicting contributions in a sensible way. In this paper, we introduce the use of a directed acyclic graph (DAG) to describe the position and Jacobian of each point of deformable models. This representation is dynamic, flexible, and allows computational optimizations that would be difficult to do otherwise. We then describe a new method for statistical cue integration method for tracking deformable models that scales well with the dimension of the parameter space. We use affine forms and affine arithmetic to represent and propagate the cues and their regions of confidence. We show that we can apply the Lindeberg theorem to approximate each cue with a Gaussian distribution, and can use a maximum-likelihood estimator to integrate them. Finally, we demonstrate the technique at work in a 3D deformable face tracking system on monocular image sequences with thousands of frames.
