LocalContrast

Simple Local Contrast Enhancement application. Features 4 methods:

Global Histogram Equalization
Adaptive Histogram Equalization (AHE)
Contrast Limited Adaptive Histogram Equalization (CLAHE)
Unsharp mask Works with color images using Lab (because contrast enhancement based on simple intensity calculated as RGB weighted sum tends to produce artifacts).

Application uses qt.conf to deploy on machines without Qt installed.

Tested with Qt 5.1 and OpenCV 2.4.9 on Windows 7. Had some issues running on Windows 8.

To build application one should edit opencv.pri according to target OpenCV version and path.

Possible improvements:

Use Gradient Domain-based approach with Poisson equation (as in single image Pseudo-HDR)
Use OpenCL for processing
Compare CLAHE performance with version provided in OpenCV
