Face Tracking with Guaranteed Framerates on Mobile Phones

Bogusław Rymut and Bogdan Kwolek: Face Tracking with Guaranteed Framerates on Mobile Phones; Image Processing and Communications Challenges 3, Advances in Intelligent and Soft Computing, Vol. 102, Springer Berlin Heidelberg, 2011, pp. 165-172.


This paper addresses the problem of face tracking with guaranteed framerates at mobile devices. The frame rate of the computationally inexpensive algorithm is not affected by the image content. An ellipse with fixed orientation is used to model the head. The position and the size of the ellipse are determined with respect to intensity gradient near the edge of the ellipse and skin color probability in the ellipse’s interior. The tracking is achieved using particle swarm optimization. The experiments were done using Lenovo S10 netbook and Nokia N900 smart phone.
