噪音图象的边缘检测
Dege Detection for Noisy Image
-
摘要: 本文描述了针对噪音图象而提出的一种新的边缘检测技术--统计边缘检测.该算法不 必对图象预处理和后处理,它以几个独立的统计试验为基础,直接区分图象和边缘和噪音.通 过对不同噪音图象的实际检测,证明本方法对噪音图象的边缘检测能力和效果几乎与对非噪 音图象的相同.Abstract: A new edge detection technique specially for noisy image -the statistical edge detection is described in this paper. The algorithm eliminates preprocessing and postprocessing for noise removal, and directly distinguishes the edge from the noise in image by several independent statistical tests. By detecting edge in different noisy images, it has been demonstrated that the edge detection capability of the algorithm for noisy image is nearly the same as that for noiseless image.
