Abstract due to the increasing traffic caused by multimedia information and digitized form of representation of images; image compression has become a necessity. new algorithms for image compression based on wavelets have been developed. The introduction of the jpegzooo compression standard has meant that for the first time the discrete wavelet transform (dwt) is to be used for the decomposition and reconstruction of images together with an efficient coding scheme. Coding scheme was developed. it applies a 2d wavelet transform on the input image data to decompose it into its frequency subbands. the baseband is losslessly coded to preserve the v. A new image compression scheme based on discrete wavelet transform has been evaluated in this work which gives sufficient high compression ratios with no degradation in quality of image.
