Hi All,
I am trying to run exampleI programs in Watershed segmetnation. I tried the example program with Input file as PGM file (in.pgm) which is of size (24*7). When I run itkWatershedSegmentationExample.cxx, I get 5 output files of raw format (with level = 0.50). When I set any of those 5 output files as an input file to second program itkWSRawToPNG.cxx so that I can convert it to png file to view, program crashes( on statement reader_update()). What should be the input file given to this second program? Also, if i want to segment the raw brest images, what reader should I use and how should i generate the output files? What filters, mappers should I use to apply watershed segmentation on grayscale breast images of Raw format to find out if there is any lesion inside the brest image? (Currently, I am using MetaImageReader to apply other ITK filters on breast images.)
Any suggestions are appreiated.
My input PGM file is as follows
