Abstract
In this brief, we present an image entropy coder, context-based bit-plane Golomb coder (CB-BPGC), for wavelet-based scalable image coding. CB-BPGC follows the idea of the state-of-the-art image coding standard JPEG2000 entropy coding to apply the rate-distortion optimization algorithm after block coding. However, it explores a more efficient block coding where statistical properties of the block coefficients are considered. Compression ratio and error resilience performances of the proposed coder are evaluated, and the experimental results show that, compared with the JPEG2000, it achieves better lossless and lossy coding performance with lower complexity and greater resilience to transmission errors when simulated on the wireless Rayleigh fading channel
