format explanation for the grounding annotation file

[peiwang062]

any explanation or instruction for how to understand the format of the annotation files, expression and labels_with_ids?
how to link each other.

[wudongming97]

Each expression corresponds to multiple frames, each frame containing multiple labels_with_ids.

Sorry for the confusion, and we will update the details.

Thanks for the reply!
I still have no idea where to start. For example, for an expression, black-cars-in-right.json, how can I find its corresponding image and associated bbox?

When you open a JSON file, its corresponding image sequence names can be found in terms of its folder name.
Our JSON file have only corresponding ids, so the corresponding box can be seen from 'label_with_ids'.
