摘要/Abstract

摘要： 用形态学滤波算子作用于红外图像,去除其中的噪声.用生长四叉树的方法获取图像中的信号尺度分布,建立尺度直方图,并据以确定形态滤波运算所要用的结构元素的最佳尺寸,从而为基于形态学的红外图像处理中结构元素的选取提供了一个客观的方法.

关键词: 形态学, 尺度直方图, 结构元素, 红外图像

Abstract: Noises in infrared images can be removed by using a filter operator of morphology. Scales of different signals are obtained by means of the constitute quad tree. The scale histogram is established and the best scale of structural elements in filter operation determined. An objective method is thus developed for selecting structural element in infrared image processing based on morphology.

Key words: infrared image, morphology, structural element, scale histogram
