Enhance contrast using histogram equalization - MATLAB histeq
J = histeq(I,n) transforms the grayscale image I, returning in J an grayscale image with n discrete gray levels. A roughly equal number of pixels is mapped to each of the n levels in J, so that the histogram of J is approximately flat. The histogram of J is flatter when n is much smaller than the number of discrete levels in I.
