My MATLAB Source Code Implementation: Histogram Equalization Algorithm

This article presents my original MATLAB source code implementation for histogram equalization, a fundamental image enhancement technique that improves contrast by redistributing pixel intensities. The code includes basic histogram calculation, cumulative distribution function computation, and intensity mapping operations. Additionally, I've included an alternative implementation written by another developer to facilitate comparative analysis of different algorithmic approaches. This allows users to evaluate variations in processing efficiency, output quality, and implementation methodologies. Looking forward, I intend to develop an adaptive histogram equalization algorithm that preserves and enhances fine image details while preventing over-amplification of noise. This advanced version would incorporate localized processing windows and contrast limiting mechanisms. I welcome any technical suggestions, code optimization recommendations, or insights regarding histogram processing techniques from the community.
