Image compression through wavelet transform coding A novel theory is introduced for analyzing image compression methods that are based on compression of wavelet decompositions. This theory precisely relates... DeVore, R.A.,B Jawerth - 《IEEE Trans.inf.theory》 被引量: 2093发表: 1992年 ...
Vector Quantization of Image Subbands: A Survey Subband and wavelet decompositions are powerful tools in image coding because of their decorrelating effects on image pixels, the concentration of energy i... PC Cosman,RM Gray,M Vetterli - 《IEEE Transactions on Image Processing》 被引量: 463发表...
If both the lower- and the higher-frequency parts are repeatedly decomposed by the decomposition filters, then the successive convolution processes correspond to a decomposition of data function by a set of wavelet-like functions, called “wavelet packet,” where there are choices whether to ...
The best wavelet packet, in the sense of the entropy, for example, within a specified number of decompositions, often provides with a powerful tool for data compression in several areas, including speech analysis and image analysis. We also note that from the viewpoint of the best basis which...

Directional wavelets JP3D H.265/MPEG-H HEVC JPEG-LS Subjective evaluation 1. Introduction Today, all modern hospitals heavily rely on digital medical imaging as an important and well-established part of the full chain of patient care handling. In fact, the completely digitized medical workflow, ...
The effects of dissimilar wavelet functions, number of decompositionsare examined in order to find optimal family for SAR images. The choice of optimal wavelets insegmentation based wavelet image compression is coiflet for low frequency and high frequencycomponent. The results presented here is a ...
