Notebook for gazed-1 test

======================================================================
Reconstructed notebook entries:
  
IMAGE ACQUISITION
  
  IBM scanner of LCS, 600 dpi, grayscale, EasyPhoto software.
  Some images were automatically normalized, all were converted
  internally to JPEG.
  
  Scanned the pieces in 10 batches data/batches/[a-j], in random order
  --- except that batch "j" has all and only the big pieces of the
  last tile (0000 through 0005).
  
  Also, for each directory "${dir}" in "data/batches/[a-j]", manually
  clipped a representative sample "${dir}/sample-raw.pgm", compute the
  histograms "${dir}/sample-raw.hist".  See "scripts/compute-scanpic-histograms".

IMAGE SEPARATION

    cd /l/sdb/staff/stolfi/hcgl/tests-for-export/glazed-1
  
    run-PZSplitExt a b c d e f g h i j
    
  This script first normalizes the gray levels of each batch
  according to the parameters in "${dir}/set-gray-levels.csh".

  Renamed fragments as listed in "data/fragments/rename-fragments.tbl"
  
  Created browse images "data/fragments/NNNN/image-small.jpg" for 
  all fragment.
  
CONTOUR EXTRACTION

    stolfi@amelia.dcc.unicamp.br 41> 
    cd /l/sdb/staff/stolfi/hcgl/tests-for-export/glazed-1
    
  Created windows for plotting:
  
    data/fragments/raw-big.wnd     (for the big pieces of batch j)
    data/fragments/raw-small.wnd   (for all the other pieces)
    
  Created links "data/fragments/NNNN/raw.wnd" to either of these,
  as appropriate.

    run-PZBoundary 0000 0402
    
  This script generates "data/fragments/NNNN/r000.{flc,ps}" from
  "data/fragments/NNNN/image.pgm.gz".  Note: coordinates are all
  in MILLIMETERS, not pixels as in the ceramic-3 test.
    
FILTERING

    stolfi@amelia.dcc.unicamp.br 41> 
    cd /l/sdb/staff/stolfi/hcgl/tests-for-export/glazed-1
 
  Created data/multiscale/NNNN for all fragments.
  Creates "data/multiscale/lambdaMin.txt" containing the 
  nominal lambda for band 001, namely 0.0625 mm (1.46 pixels).
  
  Creating "data/multiscale/NNNN/fBBB.{flc,lambda,lbl}:
 
    run-PZFilter 0000 0402
