| Abstract |
Recent surveillance technology developments motivate a regular observation of places such as coast, slopes and highways, where disasters and accidents can happen with high probability. Hence, any obvious change must be alerted. However, this is not practical for a wide area. Therefore, an automatic detection of unusual change seems to be useful and important.
In this thesis, we describe some methods which divided into online and offline approaches to detect temporal change. The online step is a 3D-2D detection using a 3D scene geometry at time A (reference) and the image of the same scene at time B (query or test). The offline step is a 3D-3D registration of 3D scenes for different times which could provide more accurate results.…… |
