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. Webinformation and pointwise mutual information. We then introduce their normal-ized variants (Sect. 3). Finally, we present an empirical study of the e ectiveness of these normalized variants (Sect. 4). 2 Mutual information 2.1 De nitions Mutual information (MI) is a measure of the information overlap between two random variables.
