Abstract :
This paper deals with fast video segmentation using active contours. Region-based active contours is a powerful technique for video segmentation. However most of these methods are implemented using level-sets. Although level-set methods provide accurate segmentation, they suffer from large computational cost. The proposed method uses a B-spline parametric method to highly improve the computation cost. Our method removes irregular sampling assumptions. It combines multi-resolution regular sampling and length penalty.
