Abstract
An automatic detection of strange parts of facilities using image processing is needed for advanced surveillance and inspection, e.g.the application of video retrieval. The image processing for an understanding of the surface status of facilities is important because of difficulty in using other sensors. This report proposes a new extraction method of slight difference of intensity such as blots on the surface of facilities. This extraction method is based on interframe difference and tracking of objects. This method is modeled on human behavior to be certain of existence of object by tracking of a uncertain object in video sequence.
