Description: The optimal predictors of a lifting scheme in the general n-dimensional case are obtained and applied
for the lossless compression of still images using rst quincunx sampling and then simple row-column
sampling. In each case, the e ciency of the linear predictors is enhanced nonlinearly. Directional post-
processing is used in the quincunx case, and adaptive-length postprocessing in the row-column case. Both
methods are seen to perform well. The resulting nonlinear interpolation schemes achieve extremely e cient
image decorrelation. We further investigate context modeling and adaptive arithmetic coding of wavelet
coe cients in a lossless compression framework. Special attention is given to the modeling contexts and
the adaptation of the arithmetic coder to the actual data. Experimental evaluation shows that the best of
the resulting coders produces better results than other known algorithms for multiresolution-based lossless
image coding.

Description: 小波分析理论是一种新兴的信号处理理论，它在时间上和频率上都有很好的局部性，这使得小波分析非常适合于时频分析，借助时频局部分析特性，小波分析理论已经成为信号去噪中的一种重要的工具。利用小波方法去噪，是小波分析应用于实际的重要方面。-The wavelet analysis theory is a new signal processing theory. It has a very good topicality in time and frequency, which makes the wavelet analysis very suitable for the time frequency analysis. With the time frequency‟ s local analysis characteristics, the wavelet analysis theory has become an important tool in the signal de-noising. Using wavelet methods in de-noising, is an important aspect in the application of wavelet analysis. In this paper,we will introduce the basic principle of lifting scheme． and present the method ofconstruction of lihing wavelets via traditional wavelets． Platform: |

Description: We propose a complete video encoder based on directional “nonseparable” transforms that allow spatial and temporal correlation to be jointly exploited. These lifting-based wavelet transforms are applied on graphs that link pixels in a video sequence based on motion information. In this paper, we first consider a low complexity version of this transform, which can operate on subgraphs without significant loss in performance. We then study coefficient reordering techniques that lead to a more realistic and efficient encoder that the one we presented in our earlier work. Our proposed technique shows encouraging results as compared to a comparable scheme based on the DCT transform. Platform: |
