Enhance and Compress the Dark Regions Depending on an Experimental Psychologist Law

This paper combines the enhance poor light image (which has reducing contrast for dark regions in image) then compresses it by recognition a background regions. At first, A Block Analysis for Gray level images method has been used to detect the background region in image by depending on an information from image block with dark regions or poor lighting. The presented work has been carried out by two steps, The first step, an information from each image block has been analyzes by A Block Analysis for Gray level images method ( i. e. background analysis based on high and low means for each block), while the second step, background for image with dark regions which has been enhanced is compressed. The aim of this paper is to detect the background image and enhance the contrast in gray level image with poor or reduced lighting then compresses it in low bit rates with good reconstructed enhanced image quality.
