Pairwise joint bivariate histograms for many variables in matlab

The following Matlab project contains the source code and Matlab examples used for pairwise joint bivariate histograms for many variables. This function combines the functionality of hist3 (joint/bivariate/pairwise histogram) and plotmatrix (pairwise scatter plots over a grid). It allows one to visualize and quantify the correlations among many variables.

Fuzzy color histogram in matlab

The following Matlab project contains the source code and Matlab examples used for fuzzy color histogram. Instead of using 3-D color histogram, we use a fuzzy inference system to build a 1_D fuzzy color histogram, which is more resistant to noise in the image, and can be used in content based image retrieval.

2d weighted histogram in matlab

The following Matlab project contains the source code and Matlab examples used for 2d weighted histogram. This function calculates a 2D, weighted histogram from: (1) an Nx2 matrix of 2D data points (2) an Nx1 vector of weights (3) M_1x1 and M_2x1 grid vectors There is an option to plot the histogram in color using the "bar3c" function (included).
