What is the format of the action masks in the original json file? #127

Closed wzcai99 closed 1 year ago

wzcai99 commented 1 year ago

After downloading the full_dataset, I extract the trajectory JSON files and try to figure out how to restore the original 300x300 image masks for actions. I noticed that in the preprocess.py file, a notation is listed that "The masks need to be decompressed". So could you please tell me how to decompress the action masks? Thank you.

In the original JSON files, the action masks seems to be a (36x2) matrix and contains large values.

@wzcai99, see this for decompress_mask. Example usage here

The masks in the JSON files are compressed masks.
