Face detection and tracking for video coding applications
Bernd Menser, Michael Brünig · 2002
In video communication applications at low bitrates, coding artifacts are especially disturbing in face areas. Encoding faces with higher quality than background regions requires automatic face detection. This paper presents a robust face segmentation and tracking algorithm and investigates the application to region-of-interest coding with H.263+ and object-based coding with MPEG-4.
