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.

为了开发流动可视化图像分析系统，本文围绕流场图像测量新方法和图像识别技术两个方面开展了研究工作。其结果推测如下：[1]。图像测量(1)推导了时空导数法的高阶近似方法，发展了油流壁面摩阻测量新技术。(2)发展了测量时均速度分布的新技术，时间平均对比法和Zaro cron计数法。图像识别(1)小波变换对图像数据的处理非常有效，能够同时处理光谱和位置。(2)模糊积分、范数和神经网络系统是有效的。
