Web简介. CLAHE 是一种非常经典的直方图均衡化算法，英文全称是 Contrast Limited Adaptive Histogram Equalization，该算法源于1994年发表的论文。. 以及Stephen M. Pizer 发表于1986年的论文 Adaptive Histogram … Ordinary AHE tends to overamplify the contrast in near-constant regions of the image, since the histogram in such regions is highly concentrated. As a result, AHE may cause noise to be amplified in near-constant regions. Contrast Limited AHE (CLAHE) is a variant of adaptive histogram equalization in which the contrast amplification is limited, so as to reduce this problem of noise amplific…
