Interest in image compression for internet and other multimedia applications has spurred research into compression techniques that will increase storage capabilities and transmission speed. This tutorial provides a practical guide to fractal and wavelet approaches--two techniques with exciting potential. It is intended for scientists, engineers, researchers, and students. It provides both introductory information and implementation details. Three Windows-compatible software systems are included so that readers can explore the new technologies in depth. Complete C/C++ source code is provided, enabling readers to go beyond the accompanying software. The mathematical presentation is accessible to advanced undergraduate or beginning graduate students in technical fields.

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. In this paper we describe the application of Discrete Wavelet Transform (DWT) for analysis, processing and compression of multimedia signals like speech and image. More specifically we explore the major issues concerning the wavelet based image compression which include choosing optimal wavelet, decomposition levels and thresholding criteria. The simulation results prove the effectiveness of DWT based techniques in attaining an efficient compression ratio of 2.67 for images, achieving higher signal to noise ratio (SNR), better peak signal to noise ratio (PSNR), while the retained signal energy is 99.9885% and the resulting signals are generally much smoother. A comparison between Discrete Cosine Transforms (DCT) and discrete wavelet transform is done finally.

Image processing requires an enormous storage, processing, and communication. To reduce this amount of data, image compression is necessary. We applied wavelet transform, which is an up coming technique and very powerful tools for signal processing, to color image compression. In this thesis, we use Daubechies 20 wavelet transform to the image compression procedure. There are five steps in the procedure. First, we extract color image into RGB components. Second, we transform RGB components to wavelet coefficients by using wavelet transform and pyramid algorithm. Third, we cut off some coefficients and scaled the results to eliminate less important data. Forth, we quantize wavelet coefficients by LBG vector quantization according to the significant of wavelet coefficients. Finally, we apply arithmetic coding, which is a lossless coding process, to wavelet coefficients. We test our algorithm with the images of Lena and Peppers. Lena is compressed with compression ratio 50-60 yielding PSNR around 34-35 and compression ratio 80-100 yielding PSNR around 30-31. Peppers is compressed with compression ratio 55-58 yielding PSNR around 34 and compression ratio 80-100 yielding PSNR around 30. Comparing with JPEG, this technique gives high PSNR than JPEG, at high compression ratio or compression ratio over 90, but less PSNR at low compression ratio or compression ratio below 85.
