A new angular point extracting method based on wavelet transform is put forward 提出一種新的基于小波變換的角點提取方法。
It extracts angular point by means of wavelet transformed modulus maximum of several scales and curvature theory 它利用在幾個尺度上小波變換模極大值和曲率理論提取角點。
The theoretical and experimental results show that the algorithm is effectire for the extracting and positioning of angular point 理論和試驗結果表明,本算法對于角點的提取和定位都是有效的。
