Patch features to region feature

[Mikhail Kim]

Hello. Could you please explain how patch features from ViT are aggregated to one specific region feature? This point is confusing, because a region doesn't necessarily contain one or several whole patches.

Hi,
sorry for my late reply.
I use image_atts to indicate a region:
