In order to realize the high speed analysis in the incoherent high particle density PIV (IHD- PIV), the further advancement in both hard and soft wares is expected. Assuming the high resolution digital pictures, a new algorithm for the PIV is proposed. Although, spatial resolutions of existing video cameras are not sufficient for the PIV, the device is still useful for the purpose, since its the real-time recording and the future advancement is expectable. Assuming that a lot of tracer images are not clearly separated in the PIV pictures on a low spatial resolution medium, a new algorithm is developed which is based on the binary-image correlation method and the velocity vector histogram method. The whole analysis process could be performed by a personal computer and its can be finished in practically short seconds.
