ImageCooccurrence

ImageCooccurrence
gives the n×n cooccurrence matrix for image.
ImageCooccurrence
computes a cooccurrence matrix for arbitrary spatial relationships specified by a kernel ker.
MORE INFORMATION
  • ImageCooccurrence returns an n×n matrix m whose elements represent the probability of all occurrences of a pixel with intensity i to the left or bottom of a pixel with intensity j, assuming all pixels to lie in one of n successive bins.
  • With ImageCooccurrence, the cooccurrence matrix can be computed for arbitrary spatial relationships specified by a matrix ker.
  • ImageCooccurrence computes the cooccurrence matrix across two images. The images must have the same dimensions.
