Abstract

Convolutional neural networks (CNNs) have recently been very successful in a variety of computer vision tasks, especially on those linked to recognition. Optical flow estimation has not been among the tasks CNNs succeeded at. In this paper we construct CNNs which are capable of solving the optical flow estimation problem as a supervised learning task. We propose and compare two architectures: a generic architecture and another one including a layer that correlates feature vectors at different image locations. Since existing ground truth data sets are not sufficiently large to train a CNN, we generate a large synthetic Flying Chairs dataset. We show that networks trained on this unrealistic data still generalize very well to existing datasets such as Sintel and KITTI, achieving competitive accuracy at frame rates of 5 to 10 fps.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The Scene Flow model is trained in highly dynamic synthetic environments and is able to estimate large flow magnitude caused by moving objects.

    “On the other hand, Scene Flow model is trained in highly dynamic synthetic environments, i.e. able to estimate large flow magnitude caused by moving objects.”

  • LiteFlowNet trained on the synthetic Scene Flow dataset can generalize well in real-world scenarios, though sometimes artifacts are present in some regions.

    “LiteFlowNet shows good generalization ability. LiteFlowNet trained on a synthetic dataset (Scene Flow(Dosovitskiy et al. 2015)) can generalize well in realworld scenarios, though sometimes artifacts present in some regions.”

  • Uzunova et al. designed a network for registration between 2D brain MRI and 2D cardiac MRI, with ground truth generated using statistical appearance models (SAMs), adapted FlowNet architecture, and obtained outperforming results.

    “Uzunova et al. (78) designed a network for the registration between 2D brain MRI and 2D cardiac MRI. Their ground truth is generated utilizing statistical appearance models (SAMs). They adapted FlowNet (79) architecture and obtained outperforming results.”

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.
