Wyrównanie histogramu

Popraw kontrast obrazu za pomocą standardowej korekcji histogramu lub CLAHE (adaptacyjna korekcja histogramu z ograniczonym kontrastem). CLAHE pracuje na lokalnych kafelkach, aby uzyskać lepsze rezultaty w przypadku nierównomiernie oświetlonych obrazów.

Popraw kontrast lokalny i globalny dzięki wyrównywaniu histogramu lub CLAHE w przypadku zdjęć, skanów i danych wejściowych CV o niskim kontraście.

Frequently Asked Questions

What is histogram equalization?

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.

What is CLAHE?

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.

When should I use CLAHE vs standard?

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.
