Mejore el contraste de la imagen utilizando la ecualización de histograma estándar o CLAHE (ecualización de histograma adaptativa limitada por contraste). CLAHE funciona en mosaicos locales para obtener mejores resultados en imágenes con iluminación desigual.
Mejore el contraste local y global con la ecualización de histograma o CLAHE para fotografías, escaneos y entradas de CV de bajo contraste.

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.
