In this paper, we report that our image analysis technique, which has be proposed for analyzing large-scale and complex simulation and measurement experiment results in nuclear field was applied to the industrial problems. The Japan Atomic Energy Agency and Nissan Motor Co., Ltd. proposed a high-speed camera using neutron radiography, and developed the technology to capture the flow of oil in a car engine. However the recorded images are blurred, it is difficult to visualize and analyze the behavior of oil in detail. Therefore, we try to overcome this by using multi-scale analysis, which is an image processing technique on image emphasis. In addition, we present a spatio-temporal image analysis for capturing the behavior of oil that is not yet understood in detail. In this presentation, we discuss the effectiveness of our image analysis technique.
