To obtain a better coding performance in wavelet-based image compression, it is necessary for wavelet filter banks to satisfy the orthogonality condition and linear phase characteristic. To satisfy these conditions, a class of IIR wavelet filters have been proposed by using allpass filters, 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 allpass filters.This method needs to transfer the side information that is used to start IIR filtering .We give a technique transfering these data efficiently.The experimental results show that the proposed wavelet filters are better than the conventional wavelets in both lossless and lossy performance. |
