Abstract: Improvements in compression performance can be achieved if the image transform is able to adapt to the shape of the objects present. We propose a new hybrid shape-adaptive orthogonal transform which is based on M-channel subband decomposition and shape-adaptive DCT techniques. The signal extension method for the region-based dyadic wavelet transform is applied to region-based image coding using M-channel filter banks. Simulation results show that the proposed method outperforms shape-adaptive DCT coding. © 2000 IEEE.
