Abstract
In this paper, we have proposed DWTSVD based contrast improvement of the digital images. The input image contrast is improved by altering intensity information obtained by applying SVD into the original image and the reconstructed approximation coefficient of the input image. The contrast of the image is enhanced by applying mask technique effectively between ISVD and reconstructed approximate, then mask image added with the original image. The proposed approach has tested for ordinary images by measuring its Peak Signal to Noise Ratio (PSNR) and Absolute Mean Brightness Error (AMBE) to check its performance.
