Basic Image Processing. www.techsource.com.my. Histogram Equalization. MATLAB essentially performs histogram equalization using this approach.Image processing is mostly a trial and error thing, and so you put a mishmash of different techniques together until you get a good result. 5 Histogram Equalization (Image Processing Using GNU Octave A MATLAB Compatible Software ). 28 December, 2016. Histogram of an image and its equalization using MATLAB. 1. To perform histogram equalization on an image, we have to make the probability density function and the cumulative density function of the image.

To perform the above operations, as well as some other basic operations, in MatLab, we use the following commands.
