VIOLENCE DETECTION METHOD BY ANALYZING THE MOTION IMAGE OF MOVING PEOPLES

摘要

PURPOSE: A violence detection method by analyzing an motion image of moving peoples is provided to accurately detect a violence situation by judging the voice information of a frame image and a variation vector within person objects within the frame image. CONSTITUTION: A background detection module detects person objects among the objects moving in a present frame image(S1000). If a center coordinate of head tracking boxes is placed in a predetermined distance, an object tracking module selects the present frame image as a violence candidate image(S3000). The object tracking module induces a change vector through acceleration information of a second head moving vector and the angle difference between head moving vectors(S4000b). If the value of the first variation vector is changed into the value within a predetermined range, the object tracking module judges the current situation as a violent state(S5000).
