Hi everybody, I have a problem that requires finding the dissimilarity between 2 binary images I tried to use the euclidean distance but the dissimilarity was large. If anyone can help me to implement such a code with a dissimilarity range between 0 and 10

If all you care about is an elementwise similarity metric that is normalized to the range [0 10]
similarity = @(A,B) 10*sum(A(:)==B(:))./numel(A);
similarity([false true true],[true true true])
Note that there are much better similarity metrics out there, but seemed like most of what you cared about was the normalization between [0,10], not how well the similarity metric works.

thank you Alex for your answer but can you please tell me what formula did you use for calculating the similarity

Absolute difference of two imagescollapse
Z = imabsdiff(X,Y)
About best selection method for image differences
Compare differences between images
h = imshowpair(A,B)
a lot of useful links
