ScholarBank@NUS Repository. https://doi.org/10.1109/76.889054||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.||Source Title:||IEEE Transactions on Circuits and Systems for Video Technology||URI:||http://scholarbank.nus.edu.sg/handle/10635/54281||ISSN:||10518215||DOI:||10.1109/76.889054|
