Determining Parameters in Contrast Limited Adaptive Histogram Equalization
نویسندگان
چکیده
Contrast Limited Adaptive Histogram Equalization (CLAHE) is an adaptive histogram equalization which was proposed by K. Zuierveld. Block size and clip limit are used to control the quality of results of CLAHE, but have been experimentally determined by users. In this paper, we propose a method to determine two parameters of the CLAHE considering the characteristics of entropy of image. Experimental results show that the proposed method enhances images with very low contrast.

A Novel Method of Determining Parameters of CLAHE Based on Image Entropy
Histogram equalization, which stretches the dynamic range of intensity, is the most common method for enhancing the contrast of image. Contrast Limited Adaptive Histogram Equalization (CLAHE), proposed by K. Zuierveld, has two key parameters: block size and clip limit. These parameters are mainly used to control image quality, but have been heuristically determined by users. In this paper, we p...

متن کاملDensity-Based Histogram Partitioning and Local Equalization for Contrast Enhancement of Images
Histogram Equalization technique is one of the basic methods in image contrast enhancement. Using this method, in the case of images with uniform gray levels (with narrow histogram), causes loss of image detail and the natural look of the image. To overcome this problem and to have a better image contrast enhancement, a new two-step method was proposed. In the first step, the image histogram is...
