Paper Abstract

This paper addresses object tracking problems in an image sequence using an active contour model called '(rho) -snake'. This model is the result of the combination of classical snakes and elements from the robust estimators theory. Snakes are energy-minimizing curves with global constraints that segment deforming shapes. The theory of robust estimators provides a framework that makes parameter estimation free from outliers. We have introduced (rho) - snakes to use these two techniques to achieve a goal: tracking a moving shape along an image sequence without being influenced by erroneous information of images. Attempting to imporve this new technique, we present parallel processing and a faster way of implementing (rho) - snakes. We also have defined robust energies, both spatial and temporal. As these energies include prediction, they fit our problem: tracking poor contrasted and fast moving object in a noisy IR sequence.
