WebMay 24, 2024 · 1 Answer. Mutual information (MI) measures how much two variables are inter-dependent. So, higher the MI, more similar the variables. Two variables could be, for example, the intensity values of two greyscale images. But many algorithms use the matching cost, i.e. how much two variables are different. Hence, the minus sign. ear looking device
