The complexity of these techniques is high and enough care has to be taken for the implementation. The aim of this work is to present a comprehensible implementation of recent variational optical flow methods. We start with an energy model that relies on brightness and gradient constancy terms and a ow-based smoothness term. We minimize this energy model and derive an e cient implicit numerical scheme. In the experimental results, we evaluate the accuracy and performance of this implementation with the Middlebury benchmark database. We show that it is a competitive solution with respect to current methods in the literature. In order to increase the performance, we use a simple strategy to parallelize the execution on multi-core processors.||URI:||http://hdl.handle.net/10553/7429||ISSN:||2254-2353||Source:||CTIM technical report [ISSN 2254-2353] Las Palmas de Gran Canaria: Centro de Tecnologías de la Imágen,n. 1, p. 1-16, (2012)||Rights:||by-nc-nd|
