IN IN807MU2014A
A camera view tampering detection system in order to detect tampering events of camera using video stream that said camera captures, said system comprising: a frame decoding mechanism; a contrast detection mechanism; a frame blurring detection mechanism; a down sampling mechanism; an illumination noise removal mechanism; a background modeling mechanism; a foreground extraction mechanism; a difference and thresholding mechanism; an illumination noise removal mechanism; a color coherence estimation mechanism; and a foreground density at background estimation; characterized, in that, said system further comprising: at least a connected foreground density estimation mechanism in order to eliminate false positives detected by said color coherence estimation mechanism and said foreground density at frame boundary estimation mechanism, said connected foreground density estimation mechanism comprising a filter bank mechanism in order to perform blob pattern analysis on frames and to generate a noise model; and at least an output generator mechanism in order to generate positive outputs in relation to camera view tampering identification based on a plurality of parameters as determined by each of said mechanisms.
