In order to develop the analysis system for a visualized image in a flow, the research work has been done in two kinds of problem : the new image measurement method for flow field and the image recognition technique. The results are surmised as follows :[1]. Image Measurement(1) Higher order approximation method for spatio-temporal derivative method has been derived and new measurement technique for wall friction using oil-flow has developed.(2) New techniques for measuring the time-mean velocity distribution have been develoned, time-averaged contrast method and zaro crons counting methed.[2]. Image Recognition(1) Wavelet transform is very effective for image data, enable to treat both spectrum and position.(2) Fuzzy integral, norm and meural network system are effective.
