[Insight-users] Texture Filter

[Karthik Krishnan]

Marshall:

Take a look at the classes : 
GreyLevelCooccurrenceMatrixTextureCoefficientsCalculator and 
ScalarImageToGreyLevelCooccurrenceMatrixGenerator. You would use the 
latter to get the co-occurance matrix and then use the former to compute 
necessary texture properties ( entropy, correlation etc. ). At present 
they calculate 4 types of coefficients, but Yyu might want to create 
variants of the GLCMTextureCoefficientsCalcultator to calculate 
additional texture features from the resulting 2D histrogram that suit 
your application.
