Abstract: According to Mallat's multiscale edge detection principle and the local features of the texture image, this paper popularizes Mallat's algorithm, which not only will be aplicable to general edge detection in the image, but also can be used to texture edge detection in the texture image.

Key words: edge detection, texture feature, multiscale wavelet transform, dyadic wavelets

摘要： 根据Malat多尺度边缘检测原理和纹理图像的局部特征,推广了Malat多尺度边缘检测算法.这个推广算法不仅适用于一般图像的边缘检测,而且还可用来提取纹理图像的边缘.
