摘要
基于正交二进小波，设计了一个滤波器对图象进行多尺度滤波，得到不同尺度的小波变换。在每种尺度下分别提取图象边缘，而后综合形成图象真正的边缘。该方法不仅能有效地抑制噪声，得到单象素宽、精确的边缘信息。
A filter based on orthonormal wavelet bases is designed to do wavelet transform with images.Different scale image edges can be detected form different scale image wavelet transform. The different scale image edges are integrated to form high accurate image edges with only a pixel width.The detctor can also be used to determainate the singularity exponent of edges so as to identfy different types of edges.
