A new angular point extracting method based on wavelet transform is put forward 提出一种新的基于小波变换的角点提取方法。
2.
It extracts angular point by means of wavelet transformed modulus maximum of several scales and curvature theory 它利用在几个尺度上小波变换模极大值和曲率理论提取角点。
3.
The theoretical and experimental results show that the algorithm is effectire for the extracting and positioning of angular point 理论和试验结果表明，本算法对于角点的提取和定位都是有效的。
