Abstract

In this paper, we propose an improved SBIHT algorithm based on double significance criteria. According to the defined relationship between a threshold and a boundary rate-distortion slope, we choose significant coefficients and trees. The selected significant coefficients and trees are quantized and entropy-coded. Experimental results demonstrate that the boundary rate-distortion slope is well adapted and the proposed algorithm is quite competitive to and often outperforms the SPIHT algorithm.
