Abstract—

Most psycho-acoustic models for coding applications
use a uniform (equal bandwidth) spectral decomposition
as a first step to approximate the frequency selectivity of the
human auditory system. However, the equal filter properties
of the uniform sub- b ....etc

Abstract
Synthetic Aperture Radar (SAR) image compression is important in image transmission and archiving. In this paper, SAR image compression using embedded zerotree wavelets algorithm, based on discrete wavelet transform (DWT), is researched. Aiming at special characteristics of SAR image such as speckle noise, the author added a denoise step in the flow of compression, trying to do some meaningful attempt in SAR image compression. Experiments carried out show that the improvement can reduce the speckle noise and improve the compu ....etc

Adaptive And Energy Efficient Wavelet Image Compression For Mobile Multimedia Data Services
ABSTRACT
To enable wireless Internet and other data services using mobile appliances, there is a critical need to support contentrich cellular data communication, including voice, text, image and video. However, mobile communication of multimedia content has several bottlenecks, including limited bandwidth of cellular networks, channel noise, and battery constraints of the appliances. In this paper, we address the energy an ....etc

Abstract
In this thesis, an adaptive compression scheme based on the wavelet transform is implemented for grayscale images. The wavelet packet decomposition of the input image is performed, and from this, a best adapted wavelet packet tree is determined. A technique for representing this tree using a bitstring is proposed. This string is included in the output stream, for reconstruction of the image. The coefficients of the transform are vector quantized and written to the output stream. The method is compared with other wavelet based compres ....etc
