IMAGE INFORMATION MASKING METHOD OF MONITORING SYSTEM BASED ON FACE RECOGNITION AND BODY INFORMATION

摘要

PURPOSE: An image information masking method of a monitoring system based on body information is provided to safely protect personal information from the outside by restricting monitoring of images transmitted from a monitoring camera to special people. CONSTITUTION: A body size of a face recognition target is measured from image information transmitted from a camera in real time(S10). A face area is extracted. A color of clothes is recognized. Size, color, and face area information are determined by comparing the size, color, and face area information with the size, color, and face area information of a special person stored in a DB(database)(S30). Similarity for the size, color, and face area information is matched when the face area is able to be recognized and determined. When similarity is more than a threshold value, the face area information is masked by using a first color(S35).
