Wavelet transformation is one of the most popular time-frequency-transformations. It is powerful feature for the signals and frequency analysis of an image. Image compression is key technology for transmission and storage of digital images. In this paper the compression algorithms are applied on various biomedical images. The algorithm used in this paper are SPIHT and EZW for comparing the quality of images after that the quality of images is compared by taking PSNR and MSE of images. Analysis of the quality measures have been carried out to reach to a conclusion.
