3D_histogram
A matlab implementation that can easily return an 3D histogram of an input image in RGB color space.
##Usage
result_table = get_3D_histogram( inputimage, X, Y, Z);
% X is the nibs in X axis, so does Y and Z;
%for example, I want an output of [100,110,120], X = 100, Y = 110 AND Z = 120.
