First Claim
Patent Images
1. An apparatus for protecting privacy information, comprising:
- an image frame division unit configured to divide a search target video sequence into a plurality of image frames;
a face detection unit configured to detect a face region from each of the image frames;
a face recognition unit configured to perform face recognition by comparing face information of a face extracted from the face region with face information of a search target face and determining whether the extracted face is substantially the same as the search target face; and
a privacy processing unit configured to distinguish between a first face determined to be substantially the same as the search target face and a second face determined not to be substantially the same as the search target face, and perform image processing to selectively mask a face region of the first face or that of the second face,wherein the second face is one of two or more faces except for the first face.
