For the blob.corners() function, what are the outputted tuple corner coordinates in respect to? Is is the center of the blob?

No, it’s just the edges of the bounding box.

If you use min\_corners() those are the edges of the rotated bounding box. The rotated bounding box is the box that fits the blob within minimum size. The regular bounding box is not rotated so it’s not necessarily the minimum fit.
