Document Type and Number:
WIPO Patent Application WO/2021/004112
Kind Code:
A1
Abstract:
An anomalous face detection method, an anomaly identification method, a device, an apparatus, and a medium. The method comprises: acquiring video information of a user (S10); dividing the video information into N pieces of sub-video information (S20); separating the N pieces of sub-video information into images under detection, and obtaining N image sequences under detection (S30); applying a feature sub-face technique to the N image sequences under detection to perform face detection, and extracting face images (S40); performing feature value extraction on face images corresponding to each segmentation node, and obtaining a face feature of each of the face images (S50); performing similarity matching on each face feature corresponding to each segmentation node, and determining whether an image of a different face is present in the image sequences under detection (S60); and if so, performing a risk notification operation for the video information of the user (S70). The method can be used to improve both accuracy and efficiency of anomalous face detection.
