.Listless zerotree image compression algorithm[J].Optoelectronics Letters,2006,2(5):376-378 Listless zerotree image compression algorithm LIAN Jing WANG Ke College of Communication Engineering, dilin University, Changchun 130025, China Abstract:       In this paper,an improved zerotree structure and a new coding procedure are adopted,which improve the reconstructed image qualities. Moreover, the lists in SPIHT are replaced by flag maps, and lifting scheme is adopted to realize wavelet transform, which lowers the memory requirements and speeds up the ceding process. Experimental results show that the algorithm is more effective and efficient compared with SPIHT. Hits: 3636 Download times: 169 View Full Text    Download reader
