We present two probabilistic formulations of the problem and carry out optimization using the RAST algorithm, a geometric matching method novel to motion estimation in video. RAST uses an exhaustive and adaptive search of transformation space and thus gives – in contrast to local sampling optimization techniques used in the past – a globally optimal solution. Among other applications, our framework can thus be used as a source of ground truth for benchmarking motion estimation algorithms.\n\nOur main contributions are: first, the novel combination of a state-of-the-art MAP criterion for dominant motion estimation with a search procedure that guarantees global optimality. Second, experimental results that illustrate the superior performance of our approach on synthetic flow fields as well as real-world video streams. Third, a significant speedup of the search achieved by extending the model with an additional smoothness prior.","lang":"eng"}],"date_updated":"2021-01-12T07:45:06Z","alternative_title":["LCNS"],"intvolume":"      4713","date_published":"2007-11-09T00:00:00Z","quality_controlled":0,"day":"09","year":"2007","publist_id":"2695","extern":1,"author":[{"last_name":"Ulges","first_name":"Adrian","full_name":"Ulges, Adrian"},{"last_name":"Lampert","id":"40C20FD2-F248-11E8-B48F-1D18A9856A87","full_name":"Christoph Lampert","orcid":"0000-0001-8622-7887","first_name":"Christoph"},{"last_name":"Keysers","first_name":"Daniel","full_name":"Keysers,Daniel"},{"first_name":"Thomas","full_name":"Breuel,Thomas M","last_name":"Breuel"}],"page":"204 - 213"}
