SUACE

Speeded Up Adaptive Contrast Enhancement (SUACE); an OpenCV based implementation of a realtime adaptive contrast enhancement technique.

SUACE is an image contrast enhancement algorithm which has been originally invented for enhancing infrared vein images. But SUACE can be used in any application which requires real-time contrast enhancement.

Features:

  1. Real-time processing
  2. Simultaneous Illumination normalization
  3. Regulated boosting for details

How to Use:

This implementation uses openCV 3.0 but can be used with openCV 2.x.x as well. Add the suace.cpp and suace.h to you project and compile with any c++ compiler. You may need to change the included openCV header files according to your version of openCV. An example code for using suace can be found in example.cpp.
