Title:
FACE MANIPULATION DETECTION METHOD AND DEVICE BASED ON OPTICAL FLOW ANALYSIS
Document Type and Number:
WIPO Patent Application WO/2024/027052
Kind Code:
A1
Abstract:
A face manipulation detection method based on optical flow analysis and a face manipulation detection device based on optical flow analysis. The device comprises: a face acquisition module configured to acquire a face video; an optical flow analysis module configured to select a plurality of adjacent frames in the face video, according to face areas detected by a face detection module, perform statistical analysis on optical flow distribution and pixel change of areas except the detected face areas for the plurality of adjacent frames, and according to a statistical analysis result, determine whether the face video has a possibility of being manipulated; and the face detection module configured to detect face areas in a plurality of continuous image frames selected by the optical flow analysis module. Face manipulation videos generated by means of PS or deep networks can be effectively detected, thereby reducing the risk of using face recognition systems.
