Function Documentation

def texture_features.eigen_texture	(		cv_image,
			blocksize = 8,
			filtersize = 3
	)

calculates eigen values of covariance matrix accumulating statistics of sobel filter responses in an image block

Parameters:

cv_image	opencv image to calculate texture over
blocksize	size of block to accumulate statistics (in pixels)
filtersize	size of sobel filter to use (in pixels)

Returns:

numpy matrix of size (width, height, 2) where [:,:,0] is the set of first eigen values and [:,:,1] is the second set
