| Research Abstract |
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.
