摘要
本文提出了一种基于邻域直方图分析的多尺度边缘检测方法.该方法分析当前象素点所处邻域内的直方图的分布特征,得到该邻域内存在边缘的可能性度量.文中分析了在边缘区内如何根据边缘宽度来定量调整样条小波的滤波尺度参数,以进行多尺度边缘检测.实验结果表明该方法可以得到令人满意的结果,同时具有较好的抗噪能力.
This paper suggests a method for determining scales for multiscale edge detection adaptively for each site in the image plane. We analyze the histgram of the neighborhood to decide edge region and plain rgion. Th edg width is analyzed in edge win to adjust th scal of cubic B spine wavelet. Finally, experiment rsults and comparsons are given. This method is proved to b eeffective and feasible by experimeent.
