基于样条二进小波的影象多尺度边缘检测

Multi-scale Edge Detection of Image Based on Dyadic Wavelet

基于样条函数理论和二进小波理论,该文研究了影象的多尺度边缘检测的理论和方法及不同样条小波系数对边缘的影响,并对遥感影象进行了实验,得到了遥感影象的不同尺度的边缘。理论和实验结果表明,基于样条二进小波的影象多尺度边缘具有良好的特性,并可用于影象匹配等研究领域。

Based on spline function theory and dyadic wavelet theory, in this paper, theory and method of edge detection are studied and multi-scale edges of image are obtained. The results show that the edge has good property and can be used for matching of images.
