Module histogram_equalization 

GPU-accelerated histogram equalization.

Provides two algorithms for contrast enhancement of single-channel (luma) images:

• Global equalization – HistogramEqualizer::equalize_luma applies a single CDF-based tone mapping to the entire image.

• CLAHE – HistogramEqualizer::clahe divides the image into a grid of tiles, clips each local histogram at clip_limit, computes tile-local equalisation tables, and bilinearly interpolates the four nearest tile tables for each output pixel.
