Image registration and image retrieval depend on image similarity measure to find mutual information between 2 images. Using histogram, joint histogram, and joint class histogram we can find the degree of similarity between those images. Hopefully, I understand and deploy both first techniques.Here, I found joint histogram algorithm and deploy using Matlab.
For example: this paper was mention this histogram and used as image similarity measurement, but I couldn't found how the authors calculate it.
However, I search for many days to find good paper, book or article regarding joint class histogram but their authors only mention this technique without enough detail. I think this technique still infant and doesn't have enough study yet.
I think joint class histogram algorithm will the best answer for my question.
