About CLAHE Local Contrast Equalizer

Global histogram equalization often over-amplifies background noise. CLAHE operates on contextual localized tiles, applies an algorithmic clip limit to suppress excessive noise peaks, and bilinearly interpolates across tile boundaries. Indispensable for underwater photography, medical scans, night shots, and dynamic range recovery.
