There are many color correction algorithms used and written. This project presents a new algorithm for digital images. This algorithm uses unsupervised enhancement with simultaneous global and local effects, called ACE for Automatic Color Equalization.

The algorithm is based on a computational model of some adaptation mechanisms of the human visual system.

 

In this project I implement the suggested algorithm and compare its results to another Matlab color correction algorithm - imadjust.

 

I implement the ACE algorithm with some adjustments that are not suggested in the paper . The results show improvement compared to the original ACE results.
