Joint entropy and histogram calculation for 3D+ images by ja

Reasonably fast. Build for any number of dimensions. (joint histogram, joint entropy, 3d)

ent(J,K,t,xyz)

Mutual Information and Joint entropy by Amir Pasha Mahmoudzadeh

Takes two images and return the mutual information and joint entropy (image processing, interpolation, registration)

Mutual_Information=MutualInformation(x,y)

Information Theory Toolbox by Mo Chen

Functions for Information theory, such as entropy, mutual information, KL divergence, etc (mutual information, relative entropy, joint entropy)

conditionalEntropy (x, y)

entropy(x)

jointEntropy(x, y)

Joint Entropy by Will Dwinnell

Calculates the joint entropy of a group of variables. (entropy, information theory, discrete)

JointEntropy(X)

ENTROPY by David Fass

Compute the Shannon entropy of a set of variables. (entropy, information theory, coding theory)
