A Resolution Progressive Image Coding Algorithm Adopting Layered Multi-threshold
【摘要】 基于WDR编码思想,结合5/3整型小波变换,采用一种新的分层多阈值的位平面扫描方案,开发了一种运算量小、内存需求低、具有分辨率渐进特性和有损无损可控制特性的图像编码算法。通过试验,表明该算法是一种简单、高效、实用的图像压缩方案。
【Abstract】 Based on the WDR algorithm,combining 5/3 integer wavelet transformation,this paper develops an image coding algorithm using a new bit-plane scanning scheme under layered multi-threshold.It has some properties of less computation,low-memory requirement,resolution progressive,lossy and lossless controllable.The experiments indicate that it is a practical image coding scheme with simplicity and high efficiency.
