the relationship of subject_id and object_id

[zhazhazhazhi]

I can't understand the relationship of this subject_id and object_id in your test_hico.json file. Whether there is a word list, can be one-to-one correspondence.

test_hico.json what is means in the subject_id , object_id . What do the numbers inside mean?
Thank you

Hi, the subject_id and object_id is the index of the box annotations list. I have found the conventional annotation file is hard to understand, and I plan to update the annotation file recently.

thanks for your reply. I understand it , but i still have a problem. for example the bbox is the cup( category_id is 4), 4 Is it a cup? I find that the list of coco is't a cup . can you give us a list for object . Let the detected people and object have a word list where the ID can be found .

'hoi_annotation': [{'subject_id': 1, 'object_id': 0, 'category_id': 5}, {'subject_id': 1, 'object_id': 0, 'category_id': 7}]

HOIW数据集里面的subject_id取值有哪些呢？ @YueLiao
