Abstract :
A new embedded lossless wavelet-based image coding algorithm called successive partition zero coder (SPZC) which use hybrid bit scanning is proposed. By successive partition the wavelet coefficients in the space-frequency domain and non-causal adaptive context modeling, SPZC outperforms other state-of-the-art coders such as SPIHT, CREW and LJPEG etc. in terms of coding efficiency even without zerotree analysis
