摘要: In this paper, we e propose an adaptive wavelet coding scheme. A decision method is designed to identify whether the LH, HL, and HH wavelet subbands are suitable for directional decomposition. The basic concept behind this decision method is to detect the large impulses in the frequency domain. The transformed data are coded by the bit-plane arithmetic code to achieve scalability. Experimental results show that this adaptive scheme has better results than the 1-D wavelet transform and the original wavelet-based contourlet scheme that applies the directional transform to all the LH, HL and HH subbands.*
