Title:
VIDEOCONFERENCING SYSTEMS WITH FACIAL IMAGE RECTIFICATION
Document Type and Number:
WIPO Patent Application WO/2022/006693
Kind Code:
A1
Abstract:
A real‐time method (600) for enhancing facial images (102). Degraded images (102) of a person –such as might be transmitted during a videoconference –are rectified based on a single high definition reference image (604) of a person who is talking. Facial landmarks (501) are used to map (210) image data from the reference image (604) to an intervening image (622) having a landmark configuration like that in a degraded image (102). The degraded images (102) and their corresponding intervening images (622) are blended using an artificial neural network (800, 900) to produce high‐quality images (108) of the person who is speaking during a videoconference.
