HISTO_CROSS
HISTO_CROSS
Computes the cross histogram of two input images. The result is an
image of dimensions (Number of slots for first image, Number of slots
for second image) which represents the density distribution of the
correlation. The value at a given (I,J) is thus the number of pixels in
the input images that have the value corresponding to slot I in the
first image and to slot J in the second one. The output image can be
used as input to task REGRESSION to evaluate some statistical parameters
of the correlation. See also HISTO_CLOUD for a slightly different
information.
