N2 - This paper is about optical flow estimation from structure tensor field analysis of a sequence seen as a spatiotemporalvolume. It tackles two issues. The first is to review related recent techniques showing their relations. We essentiallydiscuss the stages of flow extraction from structure tensor fields and the obtention of regularized tensor fields.The second is to propose a nonlinear approach controlled by the intuitive corner measure. The overall approacheswill be compared in details on serveral test sequences.
