Custom Dataset

[johnolap]

Hello,

Thanks for this great project! I have a quick question; I'm adapting the CDN code to a custom dataset. However, I can't seem to understand the format. I have converted my dataset to the VCOCO format and I was able to extract the dict keys: (['image_id', 'ann_id', 'role_object_id', 'label', 'action_name', 'role_name', 'include']) but I don't understand the pattern in the trainval.json, train.json, val.json, and test.json.

Thx for your interest in our project~

We directly apply the JSON file provided by QPIC, and you may follow QPIC to transform the annotations with their script.

Great. Thanks so much for your response.

Hi, thanks again for your reply. I have a follow-up question, The convert_vcoco_annotations.py script converts vcoco to HOIA format. But I am trying to convert a coco format annotation to HOIA by manually adding the interactions. However, I'm unable to understand a few things,
in HOIA format :
what does {subject_id , category_id, object_id} mean in "hoi_annotations" dict key,
what does {category_id} mean in "annotations" dict key"

Hi, the subject_id and object_id is the index of the box annotations list. And category_id in annotations means the category of this box.

Got it, thank you!
