| - `image_uid`: unique id to a dataset instanec | |
| - `image_path`: path to the raw rgb image | |
| - `depth_path`: path to the depth annotation of the image | |
| - `mask_path`: path to the object mask of the image | |
| - `affordance_type`: affordance type of the object in the image | |
| - `original_divisions`: there are three versions of divisions on the affordance types in the original dataset, this field stores the split ("train" or "test") of this instance in the three different divisions ("divide_1", "divide_2", "divide_3") | |
