How to know related frame of given bounding box annotations

[zeynepgokce]

Hi,
I want to learn more information about bounding box annotations in download page of Youcook2 dataset.
There is a json file that contains the bounding box annotations of the related object for validation set. But I could not obtain related frame number of given bounding boxes.
Can I obtain ground truth bounding boxes with frame of video segments ?

Not: It is not about faster-RCNN predicted top 100 bounding boxes. It is about the ground truth object bounding box annotations.

Thank you so much

I guess, the frames correspond to frames of related segment which are extracted in fps=1.
