摘要：Image enhancement aims at improving some characteristics of image to make it visually better one. One of the effective contrast enhancement techniques is histogram equalization (HE). But image enhancement methods based on histogram equalization often fail to improve local information and sometimes leading to over enhancement. In order to overcome these drawbacks, we propose a method based on modified Laplacian pyramid framework that will decompose image so that its local as well as global information is improved. HE is proposed to provide a well balanced mapping function in order to reduce quantum jump regarding global contrast.
