CLAHE Contrast Enhancer

About CLAHE

CLAHE (Contrast Limited Adaptive Histogram Equalization) improves on standard histogram equalization by operating on small regions (tiles) rather than the entire image. This preserves local contrast and prevents over-amplification.

Tile Size: Divides the image into tiles for local processing.
Clip Limit: Limits contrast amplification to prevent noise enhancement. The clipped portion is redistributed uniformly across the histogram.
Bilinear Interpolation: Tile boundaries are smoothed by interpolating between neighboring tile transformations.

CLAHE is widely used in medical imaging, satellite imagery, and photography to enhance details in images with poor lighting or low contrast.
