Book ChapterDOI
High Accuracy Optical Flow Estimation Based on a Theory for Warping
TL;DR: By proving that this scheme implements a coarse-to-fine warping strategy, this work gives a theoretical foundation for warping which has been used on a mainly experimental basis so far and demonstrates its excellent robustness under noise.
Journal ArticleDOI
Lucas/Kanade meets Horn/Schunck: combining local and global optic flow methods
TL;DR: In this paper, the authors compare the role of smoothing/regularization processes that are required in local and global differential methods for optic flow computation, and propose a simple confidence measure that minimizes energy functionals.
Proceedings Article
Highly accurate optic flow computation with theoretically justified warping
TL;DR: In this article, a variational model for optic flow computation based on non-linearised and higher order constancy assumptions is proposed, which is also capable of dealing with large displacements.
Journal ArticleDOI
Highly Accurate Optic Flow Computation with Theoretically Justified Warping
TL;DR: A variational model for optic flow computation based on non-linearised and higher order constancy assumptions, including the common grey value constancy assumption, as well as the constancy of the Hessian and the Laplacian are proposed.
Journal ArticleDOI
Optic Flow in Harmony
TL;DR: The novel anisotropic smoothness is designed to work complementary to the data term and incorporates directional information from the data constraints to enable a filling-in of information solely in the direction where the dataterm gives no information, yielding an optimal complementary smoothing behaviour.
