A novel method for designing adaptive compaction orthogonal wavelet filter banks
Hongjian Wang, Tao Chen, Silong Peng · 2004
Recently, there has been a growing interest in investigating signal-adaptive multirate filter banks. In this paper, we propose a direct method of constructing signal-adaptive orthogonal wavelet filter banks with better energy compaction performance than that of Daubechies wavelet filters of same length. The speed of this method is fast, so it can be constructed in real time.
