VIDEO SURVEILLANCE SYSTEM AND METHOD FOR FRAUD DETECTION

摘要

PROBLEM TO BE SOLVED: To provide a method and video surveillance system for detecting fraud.SOLUTION: The system receives images. The system converts the images into binary images. Subsequently, the system identifies a reference frame among the binary images. The system triggers face detection upon detecting motion within the binary images. The system detects the motion on the basis of a relative white pixel count of the binary image with respect to a reference image. The system reduces a Region of Interest (RoI) window within the binary images on the basis of the highest density of the white pixel count. The system determines whether a face is detected within the reduced RoI window. The system determines whether a mouth is detected within a lower half of the face when the face is detected. The system detects the fraud when the face is not detected or the mouth is not detected.SELECTED DRAWING: Figure 2
