This paper describes a face tracking algorithm for the development of human computer interfaces. This tracking algorithm uses a 2-D vectorial model that captures the relative positions of a set of feature points and allows the implementation of a fast multiple match scheme. This process tries to find in each frame the best arrangement of the model that minimises a measure of dissimilarity - defined as a weighted sum of absolute differences between templates representing featue points and the image. The algorithm is mainly based on a smooth motion assumption and without 3D structure head models. A complete system is described, covering aspects of automatic feature point selection, tracking, detection of tracking failures and recovery from them. The system has been implemented on a low cost platform with frame rates of up to 24 fps.
