摘要
对规则矩快速算法了进行了综述 ,包括图像变换、Delta方法、拐点方法、Green定理法和图像块表示法。提出了一种实用的规则矩快速算法———截线段法 ,该方法可对任意二值图像计算精确。以三个图像求解Hu的矩不变量为例 ,对各种算法进行了分析与比较。
This correspondence firstly gives comprehensive study to fast algorithms for geometric moments, including image transform, Delta method, computation via corner points, method based on Green′s theorem and image block representation. Then an efficient fast algorithm for the computation of regular moment is proposed. This line segment method can give accurate result for binary images. Lastly, analysis and comparison are given for various algorithms.
