Melhore o contraste e revele detalhes ocultos com equalização de histograma.
Our free online histogram equalization tool automatically enhances image contrast and improves dynamic range. This powerful technique redistributes pixel intensity values to achieve better tonal balance, revealing hidden details in shadows and highlights. Perfect for improving underexposed photos, enhancing medical images, restoring old photographs, and preparing images for analysis. All processing happens in your browser for complete privacy.
Global Equalization applies histogram equalization uniformly across the entire image. It redistributes all pixel values to span the full intensity range, maximizing overall contrast. This works best for images with uniform lighting but may over-enhance some areas.
Adaptive Equalization (CLAHE) - Contrast Limited Adaptive Histogram Equalization divides the image into tiles and equalizes each region separately. This prevents over-amplification of noise, preserves local details better, and produces more natural-looking results. Recommended for most photos and complex scenes.
