摘要
提出了一种改进的基于Delta方法的矩快速算法,解决了直接采用矩技术进行图像处理需要大量运算和Delta方法只适用于水平连续图像的问题,并应用于平面叶栅试验图像处理,得到了清晰准确的叶栅和激波图像分离结果。
A refined fast algorithm based on Delta method is developed in this paper;it solves the problem that the direet moment computation of two-dimensional images need lots of computations and the Delta algorithm can only be used in horizontally continuous images.This new algorithm is applied in image processing of two-dimensional(2-D)cascade flow field experiments.The clear image separation of cascade and shock wave is obtained.
