摘要： A video surveillance technology capable of including motion information from a plurality of surveillance cameras even when the installation conditions of the cameras are different is provided. This video surveillance system is characterized by being equipped with an extraction unit which, upon receiving video images from the plurality of cameras, extracts motion feature quantities from a plurality of frames which constitute the video images, a storage unit for storing extraction results from the extraction unit, a conversion unit for converting the extracted motion feature quantities, and an analysis unit for analyzing the converted motion feature quantities, wherein the conversion unit retains virtual coordinate axes which are different from the coordinate axes of the plurality of cameras and converts the feature quantities by calculating virtual viewpoints on the virtual coordinate axes.

摘要： An image search system comprising an video taking unit that takes a video, a search unit that contains a processor and a storage unit and searches for an image contained in the video, an input unit that receives information that is input to the search unit, and a display unit that displays information that is output from the search unit. The storage unit holds information indicating the shapes of trajectories that represent the travel paths of a plurality of moving objects extracted from the video. When information indicating the shape of a trajectory is input from the input unit, the search unit searches the plurality of moving-object trajectories held in the storage unit for trajectories that are similar to the input trajectory shape, and if such a trajectory is found, the search unit displays, on the display unit, images of the moving objects that have traveled along the found trajectories.
