Large Displacement Optical Flow: Descriptor Matching in Variational Motion Estimation

Brox, T, Malik, J·2011·IEEE Transactions on Pattern Analysis and Machine Intelligence

Abstract

Optical flow estimation is classically marked by the requirement of dense sampling in time. While coarse-to-fine warping schemes have somehow relaxed this constraint, there is an inherent dependency between the scale of structures and the velocity that can be estimated. This particularly renders the estimation of detailed human motion problematic, as small body parts can move very fast. In this paper, we present a way to approach this problem by integrating rich descriptors into the variational optical flow setting. This way we can estimate a dense optical flow field with almost the same high accuracy as known from variational optical flow, while reaching out to new domains of motion analysis where the requirement of dense sampling in time is no longer satisfied.

  • Classical optical flow estimation methods are sensitive to displacement magnitude; variational methods have advantages for small displacements, while large displacements require extra treatment and combinatorial techniques.

    “Classical optical flow estimation methods are sensitive to the displacement magnitude. Variational methods (Horn and Schunck, 1981) have clear advantages in case of small displacements, whereas large displacements require extra treatment and the use of additional combinatorial techniques (Brox et al, 2004; Brox and Malik, 2011).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
