Abstract :
In this work we propose a real time 2D parallel feature-based for image morphing and warping algorithm fully implemented in GPU (Graphics Processing Units). We applied the proposed algorithm to animate the appearance of a 3D character´s face by morphing its texture map. We compared the performance of the proposed algorithm with the sequential version implemented in CPU and the results have shown that the method is promising, being scalable on the number of features.
