Punjab Technical University Jalandhar, India deepinderkaur.bhullar@gmail.com Abstract---In this paper new image compression techniques are presented by using existing techniques such as Singular value decomposition, wavelet difference reduction (WDR) and Adaptive wavelet difference reduction (ASWDR). The SVD has been taken as a standard technique to hybrid with WDR and ASWDR. Firstly SVD is combined with WDR (SVD-WDR) and after that it is combined with its advance version that is ASWDR (SVD-ASWDR) in order to achieve better image quality and higher compression rate. These two techniques are implemented or tested on several images and results are compared in terms of PSNR, MSE and CR. IndexTerms---Compression rate (CR), Peak signal to noise ratio (PSNR), Mean square error (MSE), Joint photographic expert group (JPEG2000), Singular value decomposition (SVD), Wavelet Difference Reduction (WDR). I. INTRODUCTION One of the applications of DIP is transmission and encoding. The very first image that was transmitted over the wire was from London to New York through the medium of a submarine cable. The picture that was evacuated took three hours to grasp from one place to another.
