Title:
PERFORMANCE ANALYSIS OF VARIOUS TRANSFORM CODING TECHNIQUES USING PSNR VALUES

Abstract:
Abstract The major problem in handling the image files of photographic quality is a disk space. In such programs, images used are to be compressed for some purpose or transit and then decompressed to obtain the original quality like images. The various compression techniques were used for the above purpose. Transform coding is the base for all the compression techniques. In the transformed domain, the coefficients corresponding to the signals are subjected to quantization and bit-allocation. We could achieve a compression of 92.9% with 0.5 bits per pixel. The performance of the transform coding schemes is evaluated by computing the peak signal-to-noise ratio (PSNR). Hence, this paper analysis the performance of PSNR values over various types of transform coding techniques. For this purpose, the PSNR value is calculated for every transform coding techniques on the image of various sizes and quality factors. Based on this analysis, one can easily select the best transform coding scheme for various image sizes. Key words : Image, Compression, PSNR, Transform
