In order to realize the high speed analysis in the incoherent high particle density PIV, further advancement in both hard and soft-ware is expected. Anticipating the introduction of a high resolution CCD camera to the PIV, such an algorithm that can analyze pictures in which particle images are frequently appear being overlapped or put together is to become necessary. The new algorithm is based on the binary-image correlation method and the velocity-vector histogram method. The analysis can be finished in practically short seconds on a personal computer.
