Abstract :
We generalize to 3D shaped mosaics the generative video representation of video sequences introduced by Jasinschi and Moura (see Proceedings of the IEEE International Conference on Image Processing, Washington DC, USA, October 1995). Using a parametric representation of the 3D shape, we recover the 3D shape and 3D motions from the 2D motions in the video sequence. We consider piecewise planar object shapes under orthography and demonstrate our approach with a real life video clip
