一种新的亚取样图象内插方法——基于SHSF－AMS的误差扩散算法

A NEW INTERPOLATION ALGORITHM BASED ON SHSF AMS AND SCATTERED ERROR FOR SUBSAMPLED IMAGE

亚取样／内插是一种快速简便有效的图象压缩编码方法，是高分辨率电视压缩编码中的一项重要技术．本文提出了一种新的亚取样图象内插算法即基于尖帽函数型联想记忆系统ＳＨＳＦ－ＡＭＳ的误差扩散算法．

Subsampling/Interpolation is a simple, fast, and effective method for image compression coding, and one of the important techniques in HDTV compression coding. In this paper, a new interpolation method, which is based on the SHSF AMS and scattered error, is proposed for 1/2 subsampled image. The computer simulations show that the new interpolation algorithm has better performance in comparison with existing interpolation algorithms.
