Application of Adaptive Wavelet Transforms via Lifting in Image Data Compression

摘要：

The adaptive wavelet transforms via lifting is proposed. In the transform, update filter is selected by the signals character. Perfect reconstruction is possible without any overhead cost. To make sure the systems stability, in the lifting scheme of adaptive wavelet, update step is placed before prediction step. The Adaptive wavelet transforms via lifting is benefit for the image compression, because of the high stability, the small coefficients of high frequency parts, and the perfect reconstruction. With the adaptive wavelet transforms via lifting and the SPIHT, the image compression is realized in this paper, and the result is pleasant.
