An Efficient Combination of 2D and 3D Shape Descriptions for Contour Based Tracking of Moving Objects

Tracking the 2D contour of a moving object has widely been used in the past years. So called active contour models have been proven to be a promising approach to real-time tracking of deformable objects. Also tracking 2D contours, which are projections of rigid 3D objects, is reduced to tracking deformable 2D contours. There, the deformations of the contour are caused by the movement in 3D and the changing perspective to the camera.
