Book Description
The fast development of multimedia computing has led to the demand of using digital images. The manipulation, storage and transmission of images in their raw form is very expensive, and significantly slows the transmission and make storage costly. Efficient image compression solutions are becoming critical with the recent growth of data intensive, multimedia based applications. Many techniques are now available and much effort is being expended in determining the optimum compression transforms. Compression is done using Cosine and Wavelet Transforms. Recently compression techniques using Wavelet Transform (WT) have received great attention, because of their promising compression ratio, ability to analyze the temporal and spectral properties of image signals and flexibility in representing non stationary signals like speech and images by taking into account human perception system.
