Negative Frames Matter in Egocentric Visual Query 2D Localization. (arXiv:2208.01949v1 [cs.CV])

The recently released Ego4D dataset and benchmark significantly scales and
diversifies the first-person visual perception data. In Ego4D, the Visual
Queries 2D Localization task aims to retrieve objects appeared in the past from
the recording in the first-person view. This task requires a system to
spatially and temporally localize the most recent appearance of a given object
query, where query is registered by a single tight visual crop of the object in
a different scene.
