Color similarity matrix?

I am quite new with MATLAB so my question may sound silly. I have 200 .jpg image files loaded in MATLAB. I would like to create a color similarity/dissimilarity matrix to see how much each image is similar or dissimilar compared with the others. How could I achieve it? Is there any toolbox that is specific for that?

You can first compare two images then extend the method to compare multiple images.

The comparison involves two steps :

1.) Feature detection and extraction

2.) Extracted feature comparison.

Now , there are several methods to detect and extract features. But , since you are specifying color comparison , one way could be by calculating the color histogram and then comparing the color histograms by the the built in functions available in MATLAB

Thank you for your answer.

Would you mind telling me whether there are any toolbox that are specific for doing that or any pre-installed function that are specific? Thank you again
