Halcon clahe
WebAdaptive histogram equalization (AHE) is a computer image processing technique used to improve contrast in images. It differs from ordinary histogram equalization in the respect that the adaptive method computes several histograms, each corresponding to a distinct section of the image, and uses them to redistribute the lightness values of the image.It is … WebCLAHE uses a clip limit to prevent over-saturation of the image in homogeneous areas. These areas are characterized by a high peak in the histogram of an image tile due to many pixels falling in the same …
