HISTO_DOUBLE

HISTO_DOUBLE
Computes the histogram of an image (Y_image) as a function of a sec-
ond one (Z_image). This gives an information similar to, but
slightly different from the cross histogram (cf HISTO_CROSS). The
program computes histogram of the mean value and standard deviation.
The result is a table of 4 Columns, in which
1) the first column contains the mean value of the Y_image (average
of all pixels in the Y_image for which the Z_image value is included
in the corresponding slot)
2) the second the standard deviation (of the Y_image values).
3) the third the number of pixels of the Y_image used to compute
the mean and deviation.
4) the fourth column contains the histogram abscissa (actual value
of the input Z_image)
