How can mutual information in images be presented quantitatively?

I need a measure which results in 0 or 100 if 2 RGB images being tested are same, and give different value if there is some dissimilarity in them. The number should represent mutual information.

What is your perception on using visual analysis or quantitative approaches to evaluate data from single-case research designs (n of 1 trials)?

Results of single-case research designs (i.e., n-of-1 trials) are often evaluated by visually inspecting the time-series graph and computing quantitative indices. A question our research team is...
