Dense Annotations -> Epic Kitchens Frame Mapping

[egeozguroglu]

Hi Team,

One clarification question regarding your VISOR -> Epic Kitchens frame index mappings:

On the VISOR README, it is mentioned that the Ground Truth - Sparse Annotations' frame number, as specified by the image_path field does not necessarily match the Epic Kitchens frames and that the correct mapping is provided through frame_mappings.json: "Note that this might not exactly match the EPIC-KITCHENS frame numbers (see Sec frame extraction for correspondences)"

Does this also apply to your "Interpolations - Dense Annotations"? Or is frame_mappings.json ONLY for purposes of the GT Sparse annotations. In other words, is the 1:1 mapping between dense annotations and epic kitchens frame numbers correct without frame_mappings (as specified in the EPIC_KITCHENS_VISOR/Interpolations-DenseAnnotationsJSONs)?

Thanks,
Ege

Have the same question. Following up on this.

You need to refer to the other repo:
https://github.com/epic-kitchens/VISOR-FrameExtraction
This is where you can extract the frames for the dense annotations -- we have not released all the frames as they are large. Once you extract these frames they will directly correspond to the released dense annotations
