Efficient Brightness Preserving Enhancement Algorithm for Images in Consumer Electronic Devices

Abstract

Image enhancement improves the image quality so that the resultant image is better than the original image for a specific application or set of objectives. Image enhancement is the task of applying certain alterations to an input image so as to obtain a more visually pleasing image. A simple and effective enhancement method, the Histogram Equalization (HE) technique has its major disadvantage of hampering the mean brightness of the image. So, it is not likely to use HE in consumer electronic products. The main objective of this paper is to propose an efficient enhancement algorithm for images in consumer electronic devices which will produce a vivid colored enhanced image with better PSNR. In this regard, a novel technique which is a modification of Minimum Mean Brightness Error Dynamic Histogram Equalization (MMBEDHE) has been proposed.
