Abstract
A video surveillance system, including motion information from a plurality of surveillance cameras even when the installation conditions of the cameras are different, is 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.
