Clahe histogram
WebCLAHE (Contrast Limited Adaptive Histogram Equalization) The first histogram equalization we just saw, considers the global contrast of the image. In many cases, it is not a good idea. For example, below image … WebJan 8, 2013 · CLAHE (Contrast Limited Adaptive Histogram Equalization) In adaptive histogram equalization, image is divided into small blocks called "tiles" (tileSize is 8x8 by default in OpenCV). Then each of these blocks are histogram equalized as usual. So in a small area, histogram would confine to a small region (unless there is noise).
