METHODS FOR DEFINING, DETECTING, ANALYZING, INDEXING AND RETRIEVING EVENTS USING VIDEO IMAGE PROCESSING

摘要

Methods and systems for defining, detecting, analyzing, indexing, and retrieving events using video image processing techniques are described herein. An illustrative method of detecting and analyzing events occurring within a region of interest of a video monitoring system may include the steps of extracting information regarding one or more objects located within a region of interest, analyzing the extracted information to detect the occurrence of one or more events within the region of interest, matching at least one of the detected events with a corresponding user-specified event, and performing an action response upon the detection of such an event. In certain embodiments, the detected events may be defined as a set of semantic parameters relating to the object's state and/or physical features, which can be compared against a corresponding set of semantic parameters programmed within a video image-processing appliance manager.
