On the Image enhancement histogram processing
Jinwen Yang, Weihe Zhong, Zheng Miao · 2016
With the using of Image processing widely. Image enhancement technology has become a hot research field of image processing recently, it can improve the quality of images. This article mainly introduces two aspects, namely, histogram equalization processing and provision of enhanced methods. Meanwhile, compared the pre-processing with post-processing, the relative formulas and standard digital images have been shown in this paper. The experimental results have shown that the histogram equalization and specifications can improve the contrasted effect. According to the algorithm of histogram equalization and specifications, intensive gray distribution of the original image has become more sparse, so the image processing visual effects and its contrast can be improved.
