DCT SVD Based Hybrid Transform Coding for Image Compression

Abstract

Image compression is one of the existing research areas in the field of multimedia. In this paper we are proposing a novel scheme for image compression using discrete cosine transform and singular value decomposition. It is proposed that discrete cosine transform of the image can be truncated. For this truncated discrete cosine transformed matrix, singular value decomposition is applied. The Singular Value Decomposed matrices can be truncated and the truncated matrices are multiplied and transmitted. The effort is made to compare the techniques with only DCT in terms of PSNR, Compression Ratio and computational complexity. The experiment is done for different set of file formats.
