Local Equalization

This plugin proceeds in every pixel to a local equalization of the luminosity, with a matrix of 17x17 pixels. From an artistic point of view, local equalization can be interesting if you wish to stress the aspect of a given texture. But this process can be also used to analyze an image where certain details are barely perceptible.

Example 1: From left to right: the original texture, the result of the local equalization, and the final result obtained by blending the effect at 20 %.

Example 2: The image below was provided with an old verion of Photoshop. Note the explosion of details.

Before After

Remark: It is not recommended to use highly compressed images because local equalization reveals even more compression artifacts. (especially .jpeg)
