主 题:Image compression set partitioning in hierarchical tree (SPIHT) MSPIHT entropy coding peak signal-to-noise ratio (PSNR) compression ratio.
摘 要:In this paper, the authors propose a new approach to image compression based on the principle of Set Partitioning in Hierarchical Tree algorithm (SPIHT). Our approach, the modified SPIHT (MSPIHT), distributes entropy differently than SPIHT and also optimizes the coding. This approach can produce results that are a significant improvement on the Peak Signal-to-Noise Ratio (PSNR) and compression ratio obtained by SPIHT algorithm, without affecting the computing time. These results are also comparable with those obtained using the Embedded Zerotree Wavelet (EZW) and Joint Photographic Experts Group 2000 (JPG2) algorithms.
