Abstract:

By combining Zerotree, bit plane and arithmetic coding together, a new image compression algorithm based on Zerotree and bit plane called ZBP is presented in this paper. ZBP exploits the correlation among the Zerotree symbols and the bit data of wavelet coefficients, so the efficiency of arithmetic coding is improved. Experimental results demonstrate that ZBP performs better compression than the existing wavelet imagecompression algorithms.
