Colored digital images are extensively used in computer applications. Uncompressed digital images require considerable storage capacity and transmission bandwidth. Efficient image compression solutions are becoming more critical with the recent growth of data intensive, multimedia-based web applications. This book studies color image compression with discrete Cosine, Fourier and Wavelets (Haar and Daubechies) transforms. As a necessary background, the basic concepts of color images, Wavelets and recently used compression algorithms are discussed. In the end, comparison of different transforms using different color image has been given.
