Role of Global Contrast in Global-Local Contrast Enhancement
Main Article Content
Abstract
For most of the low contrast images, applying the local contrast enhancement along with global contrast enhancement is much better
than that of global contrast enhancement only or local contrast enhancement only. Such Global-Local contrast enhancement methods improve
the quality of low contrast images in global contrast as well as local contrast whereas global contrast enhancement methods improve the quality
of an image in global contrast only and local contrast enhancement methods improve the quality of an image in local contrast only. However,
among the Global-Local contrast enhancement methods, the global contrast enhancement method plays a great role for the enhancement.
