Une approche globale à l’estimation du mouvement de caméra pour des scènes encombrées
This master’s thesis is a research in the field of computer vision and deals with egomotion estimation from a video sequence. Solving egomotion can lead to many applications, like automated navigation for instance. We analyse videos of cluttered scenes, composed … Continue reading

(English) MRF solutions for probabilistic optical flow formulations
Abstract In this paper we propose an efficient, non-iterative method for estimating optical flow. We develop a probabilistic framework that is appropriate for describing the inherent uncertainty in the brightness constraint due to errors in image derivative computation. We separate … Continue reading
