摘要
本文介绍了一种用于离散色图像边缘平滑处理的表决法,比较了它和平均法、中值滤波法的异同及合理性。以实例说明了选取窗口时利用周期匹配的原理可使某一类边缘(如45度走向的锯齿形)达到最理想的平滑结果。针对空间离散化带来的具体问题,给出了几种实用的算法并作了比较。同时,还简介了若干特殊要求的处理方法。
This paper introduces the' vote method 'of edge smoothing for discrete - color images, and discusses its differences and rationalities between this method and average and median filter methods. Certain examples are used to illustrate that selecting windows by the use of resonance principle can make some kinds of edges( e.g. saw - tooth at an angle of 45 degrees) get the smoothest results. Considering dimensional discretization,several algorithms and their differences are detailed. Moreover, this paper introduces the way to satisfy some special requests.
