Lossy Image Compression Using Hybrid SVD-WDR

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract -In this paper a new image compression technique is presented using Singular value decomposition (SVD) and wavelet difference reduction (WDR). In this we have done hybridization of these two techniques in order to achieve higher compression rate and better image quality. The first technique that is SVD provides high image quality and low compression rate whereas, the other technique that is WDR provides high compression rate but low image quality. The methodology used for the proposed technique is as follows: First image is compressed by using SVD and then again compressed by using WDR technique to acquire better results for compression rate and image quality. The proposed technique is tested on several images and the results are compared with JPEG2000, WDR, SVD in terms of PSNR and MSE. The results obtained by the proposed technique have shown superiority to the several state-of-art techniques.
