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.

Alex's formula is simply the percentage of pixels in A that match in B.
Here's another one called the Sorenson-Dice Coefficient: http://www.mathworks.com/matlabcentral/answers/68720#answer_80012

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
