METHOD AND SYSTEM FOR IMPROVING PERFORMANCE OF INTELLIGENT SURVEILL SYSTEM USING PSNR

摘要

PURPOSE: A method and a system for improving the performance of an intelligent monitor system using a peak signal-to-noise ratio (PNSR) are provided to improve the performance of an intelligent monitor system by processing video data from a plurality of fixed cameras and playing the video data only using frames ordered to play. CONSTITUTION: A video signal stored in the buffer (102) of a PSNR calculator (104) and an input video signal transmitted from a video acquisition unit (100) are stored in order to calculate a PSNR between the video signal and the input video signal. An update decision unit (106) stores the input video signal to the buffer if the PSNR is lower than a predetermined first value. The update decision unit does not store the input video signal to the buffer if not. An image analysis unit (108) analyzes the video of the video signal when a new video is stored in the buffer.
