"Webb23 juni 2024 · In histogram equalization, we want to go from a low contrast plot into a high contrast plot. Our goal in histogram equalization is to go from a given distribution to a uniform distribution assuming that pixel values can go from zero to \ (L – 1\). For example, standard L is 256, so we can go from 0 (dark) to 255 (very bright or white). " - Histogram equalization python实现
