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

Claims the paper makes

We couldn’t retrieve this paper’s full text, 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?

  • Spatiotemporal Gabor filters have been used in several models of the response of motion selective neurons in the visual cortex.

    “Spatiotemporal Gabor filters have been used in several models of the response of motion selective neurons in the visual cortex [57], [59], [39].”
  • Using a single scale of filters was not sufficient because optical flow was not computed in fast moving regions of several video sequences due to temporal aliasing.

    “We found that using a single scale of filters was not sufficient, since optical flow was not computed in fast moving regions of the several video sequences due to temporal aliasing [60], [57].”
  • It is important not to combine estimates across scales due to temporal aliasing.

    “It is important not to combine estimates across scales due to temporal aliasing [57], [60].”
  • Responses of several spatio-temporally separable responses can be combined to encode the local speed and direction of motion of the video sequence.

    “Further, the responses of several spatio-temporally separable responses can be combined to encode the local speed and direction of motion of the video sequence [57], [58].”
  • Translational motion has an easily accessible representation in the frequency domain.

    “Translational motion has an easily accessible representation in the frequency domain and these ideas have been used to build motion estimation algorithms for video [8], [57], [58].”

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.
