An image compression method is applied on the EZW and WDR. These techniques are more efficient and provide a better quality in the image. In compression, wavelets have shown a good adaptability to a wide range of data, while being reasonable complexity. The above techniques have been successfully used in many applications. The techniques are compared by using the performance parameters PSNR and MSE has been successfully implemented to provide high compression rates maintaining ratio can be reached to good quality of the image with different level wavelet codes. The objective of this paper is to implement the concept of wavelet based image compression to gray scale images using different techniques. The techniques involved in the comparison process of EZW and WDR.
