Abstract : Image compression is very important in the present scenario. The compression is not only the main objective but also the image quality is an important factor which should be kept in mind for choosing any compression method. In this paper we will discuss the necessity of hybrid coding over classical coding schemes and why DCT – DWT hybrid approach is so important among various hybrid schemes. The goal is to achieve higher PSNR i.e. peak signal to noise ratio where original image means signal and the noise is error in reconstructed image.
