Abstract

THE PRESENT INVENTION PROVIDES A SYSTEM FOR DETECTING INTRUSION EVENT IN REGION OF INTEREST. THE SYSTEM (100) COMPRISING AT LEAST ONE BLOB SEGMENTATION SUB-COMPONENT (102), AT LEAST ONE BLOB PROPERTIES COMPUTATION SUB-COMPONENT (104), AT LEAST ONE BLOB FILTERING ANALYSIS AND VALIDATION SUB-COMPONENT (106), AT LEAST ONE BACKGROUND MODEL UPDATE SUB-COMPONENT (108) AND AT LEAST ONE INTRUSION EVENT ANALYSIS SUB-COMPONENT (110). THE SAID BLOB SEGMENTATION SUB-COMPONENT (102) PROCESSES CURRENT IMAGE AND EXTRACTS MOTION PIXELS BY SUBTRACTING CURRENT IMAGE FROM REFERENCE OR BACKGROUND IMAGE. THE SAID BLOB PROPERTIES COMPUTATION SUB-COMPONENT (104) CLASSIFIES MOTION PIXELS BY APPLYING MORPHOLOGY CLOSING AND FILING HOLES TO CURRENT MOTION MAP AND LABELING EACH OF ADJACENT MOTION PIXELS. THE SAID BLOB FILTERING ANALYSIS AND VALIDATION SUB-COMPONENT (106) VALIDATES INTRUDER BLOBS USING RULE SET WHICH COMBINES INFORMATION OF CALCULATED PROPERTIES. THE SAID BACKGROUND MODEL UPDATE SUB-COMPONENT (108) UPDATES BACKGROUND IMAGE USING COMBINATION OF RULES BASED ON SIMILARITY VALUE OF DETECTED BLOB AND ITS SURROUNDING BY UPDATING PIXEL IN BACKGROUND IMAGE USING PREDEFINED INCREMENT OR DECREMENT VALUES IF CURRENT PIXEL IS BACKGROUND PIXEL AND UPDATING BACKGROUND PIXEL WITH CURRENT PIXEL INTENSITY IF CURRENT PIXEL BELONGS TO MOTION BLOB AND BLOB IS NONSIGNIFICANT WHILE THE SAID INTRUSION EVENT ANALYSIS SUB-COMPONENT (110) TRIGGERS ALERT WHEN EVENT IS DETECTED AND VERIFIED. ANOTHER EMBODIMENT OF THE PRESENT INVENTION PROVIDES A METHOD (700) FOR DETECTING INTRUSION EVENT IN REGION OF INTEREST. THE METHOD COMPRISING THE STEPS OF PROCESSING CURRENT IMAGE AND EXTRACTING MOTION PIXELS (702), CLASSIFYING MOTION PIXELS (704), DETERMINING INTRUDER BLOBS USING COMBINATION OF RULES BASED ON BLOB GEOMETRIC PROPERTIES, TEMPORAL PROPERTIES AND SIMILARITY PROPERTIES OF BLOB WITH SURROUNDING PIXELS (706), UPDATING BACKGROUND IMAGE USING COMBINATION OF RULES BASED ON SIMILARITY VALUE OF DETECTED BLOB AND ITS SURROUNDING (708) AND TRIGGERING ALERT WHEN EVENT IS DETECTED AND VERIFIED (710).
