Histogram equalization redistributes pixel intensities so the histogram spans the full range (0–255). This improves contrast, especially in images that are too dark or too bright.
CLAHE (Contrast Limited Adaptive Histogram Equalization) applies equalization locally on tiles rather than globally. It prevents over-amplification of noise by clipping the histogram, producing more natural-looking results.
Use standard equalization for uniformly lit images. Use CLAHE for images with uneven lighting, shadows, or when you want to preserve local detail without over-boosting contrast.
