Perspective deformations on the image plane make the analysis of object behaviors difficult in surveillance video. In this paper, we improve the results of trajectory-based scene...
This paper presents a new interaction technique for browsing large visual information bases in a collaborative environment. The ATELIER project deals with learning environments fo...
A family of structure from motion algorithms called the factorization method has been recently developed from the orthographic projection model to the afJine camera model [23, i6,...
