In this paper, we propose a global method for estimating the motion of a camera which films a static scene. Our approach is direct, fast and robust, and deals with adjacent frames of a sequence. It is based on a quadratic approximation of the deforma

International audience; The layer model describes images as the projection of a three dimensional scene composed of several opaque objects located at different depths from the camera. The background is the last layer, and the moving objects are proje
