An important application domain of the wavelet theory is compression. In this paper, we use wavelet transforms to compress two different types of images (i) medical images (Echo image), (ii) color images, by using two different procedures. We use different types of wavelet transforms. Further, the compression ratio, the bits per pixel and the relative 2-norm difference are calculated. The quantitative measures are used to compare and contrast the performance of different wavelet transforms.
