[Insight-users] Submission: itkScalarImageToGreyLevelCooccurrenceMatrixGenerator

[Zachary Pincus]

Hello,

Here is my revision/rewrite of Glenn Pierce's Cooccurrence List filter.
Basically, when given an image and a set of offsets, this generator 
produces a histogram of the pixel value co-ocurrences between each 
pixel and the various pixels at the given offsets from that pixel. (See 
the documentation in the header for more information.)

This is typically called a "Grey Level Co-occurrence Matrix" (GLCM) and 
it is used in calculations concerning the texture of various objects. 
In the next week, I hope to contribute code for calculating texture 
descriptors from GLCMs. These descriptors are often used in computer 
vision/statistical learning tasks to classify different image patches 
by texture. I hope that others will find these tools useful...

Implementation note: after thinking about the best way to do things, it 
really seemed like enough special things needed to be done between 
making a list of values and making a good GLCM that it was worth it to 
make a special GLCM generator, instead of a list adaptor.

Zach
