Number of needed RGB images for a custom object in my own custom dataset

[monajalal]

Could you please suggest what would be a sensible number of frames for training CenterPose for a single custom class (in my own custom dataset)?

I have synthetic images and each image may contain up to 3 types (3 different CAD types) of the the same custom class.

I would like to know if you have suggestions on what would be a reasonable number of images for training purposes to get sensible results on real-world data of the same class.

Thanks a lot for your impressive work.
