| 摘 要： | 提出了一种用小波变换检测图像边缘的新方法。它基于小波变换多尺度方法分析图像局部的直方图内的信息,通过对小波变换后直方图内信号零交叉点的检测,得到一序列门限值点用于描述图像的边缘即可检测出图像边缘。选取不同的尺度可得到不同分辨率的图像边缘。文中介绍了小波变换用于图像边缘检测和基本原理,给出了小波变换的快速算法和实际检测结果。

| Abstract: | A new methord is proposed to detecting multiscale edges of image with wavelet transform.It is based on the wavelet transform which provides a maltiscale analysis of information of the histogram of an image.By the de tection of the zero-crossings of the wavelet transform of the histogram,a seguenee thresholds of the histogrsm is obtained,which is used to describe the image edge features. |
