【Abstract】 Introduces the two-dimension wavelet decomposition and construction algorithm and its engineering application in image manipulation. In this paper, the practical arithmetic approach of resolving and re-comprising is analyzed. A study is presented about how to apply the arithmetic to image compressing, and some examples of the application are analyzed. As the results show, larger compressing ratio of image can be obtained by the application of this arithmetic approach. So that image manipulation with wavelet technology has such characteristics as high compression ratio,rapid speed,stable feature,etc.更多还原
