Abstract: The method for video-data indexing using a map comprises the following steps: video data are obtained from at least one camera; the video data are used to locate at least one moving object and to estimate the object position and/or motion parameters in a two-dimensional video frame coordinate system (the object position on the video frame); the position and/or motion parameters of the located object are converted from the two-dimensional frame coordinate system into a two-dimensional map coordinate system (the object position on the map); at least one index record is generated to relate the video data containing the located object to its position and/or motion parameters on the map; the index record is saved in the database and/or storage. The invention accelerates and refines search requests for video data containing information about objects moving across the area under video surveillance.

Abstract: This Invention deals with data processing methods. This method involves the receipt of video data from a video camera and transmission of ranked video data to a user and/or to storage via communication links. Received live video data is first segmented based on at least one object and/or event; then, each segment is analyzed for characteristics that are critical for the priority estimate of a segment and/or used to search for segments in the storage. Each segment is prioritized based on its characteristics. Segments are ranked based on their priority estimates; the resulting priority queue of segments or one segment of the highest priority is transmitted to a user and/or recorded into storage. This Invention reduces load imposed on limited bandwidth communication links and improves video data processing without sacrificing video quality. 25 subclaims; 4 figures; 3 tables.
