摘要
讨论了一种新的边缘检测方法和用链码描述的线矩数学模型，给出了基于不变线矩匹配的约束条件，并采用基于特征与最小二乘结合实现了精确的子像素匹配。
A new edge detection method and mathematical model of line moment described by chain code are discussed in this paper. The constraints of line moment invariant based matchimg are presented,and exact sub pixel matching is realized by feature based and least square method .
