摘要：Histogram equalization is an essential technique in Image Processing. It is a contrast adjustment process using image histogram. Contrast upgrade is an imperative zone in image processing for both human and PC vision. Different Methods are proposed and some extraordinary Image Histogram strategies are Adaptive Histogram Equalization system, Recursive mean square histogram adjustment, and Global Histogram balance. In this paper, impressive histogram equalization method by changing mega pixel value is implementing. We consider some of the pixel value between ranges and then calculate its cumulative frequency. After equally distribution intensity is mapped to get a new intensity value a new histogram value.
