| Abstract(in English) | To obtain a better coding performance in wavelet-based image compression, it is necessary for wavelet filter banks to satisfy orthogonality condition and linear phase characteristic. To satisfy these conditions, a class of IIR wavelet filters have been proposed by using a complex allpass filter, and then a better coding performance has been obtained for lossy image coding. In this paper, we propose an effective implementation of reversible wavelet transform by using a complex allpass filter. The experimental results show that the proposed wavelet filters can obtain a comparable lossless performance and a better lossy performance at low bitrate than the conventional wavelets. |
