【Abstract】 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.更多还原
