[Octave-bug-tracker] [bug #54974] [octave forge] (image) incompatible results of entropy.m

[Avinoam Kalma]

Update of bug #54974 (project octave):

                  Status:                    None => Confirmed

Follow-up Comment #3:

Reading Matlab documentation:

"entropyfilt converts any class other than logical to uint8 for the histogram
count calculation so that the pixel values are discrete and directly
correspond to a bin value",

So if you use in the examples:


C = uint8([1 1 1; 2 2 2; 3 3 3]);
D = C';
E = uint8(ones (3,3));
E(2,2) = 2;
F = uint8(3 .* ones (3,3));
 

You will see that Octave results are similar to Matlab results, on uint8
matrices.
