A Colour Tracking Procedure for Low-Cost Face Desktop Applications

In this paper we present an environment for the tracking of a human face obtained from a real video sequence. We will describe the system and discuss the advantages and disadvantages of our approximation. We mainly focus on the situation of the main attributes of the human face (eyes, eyebrows, nose and moth). The tracking algorithm and the ulterior animation of the synthetic model must guarantee the real time response without the need of any additional markup of the actor. Due to the complexity of the process, we make an initial selection of the facial attributes involved without any efficiency or robustness loss. We define a probabilistic model of skin face area and we would like to track this region in the sequence of images. In parallel we propose additional criteria to search inside this tracked area main features in human face (as lisp, eyes, eyebrows, nose, etc..). The tracking algorithm is based in a efficient implementation of continuously adaptive mean shift procedure (CAMSH...
