摘要
本文提出一种新的矩和矩的不变性。它不仅适合于封闭轮廓线的识别和匹配,而且可以用来进行任意曲线段以任意方式组合所构成的物体的识别和匹配,从而拓广了前人平面矩、付里叶描述子等方法的应用范围。同时运用本文方法更正了前人方法的错误。最后,为了有效地使用曲线矩,本文提出了曲线矩计算的快速算法。新算法几乎不需要乘法,因此实现简单,速度快。
The curve moment and curve moment invariants are proposed, which aresuitable to be used not only in the pattern recognition of closed shapes, but also in that of any curved objects. By using the proposed moments, some errors of the known methods are corrected. Finally, a simple algorithm is proposed to calculate curve moments.
