In the dissertation, it is introduced about the development and the main of methods of particle image analysis in the fluvial experimentation of harbor & channel engineering.

Based on grey-scale statistic classification,this paper presented a new simultaneous measuring technique for the velocity and size of planar particle image in real-time,called PIVS(Particle Image Velocimetry & Sizer).

In this paper, the local characteristics statistics of particle image-unified greyness statistical frequency is suggested, and its peak value is analysised.
