边沿检测与噪声消除方法研究

STUDY ON THE METHOD OF EDGE DETECTION AND NOISE REDUCTION

应用灰度台阶的概念 ,对二值图像和灰度图像的噪声与边沿的特征进行分析 ,给出边沿与噪声的本质特征 ,并给出区分噪声与边沿的函数关系式 ,据此公式 。

Base on the conception of gray scale, the noise and edge feather of binary image and gray scale image is analyzed. According to the function of relation between noise and edge, the procession of edge detection and noise reductioncan be finished easily.
