Misidentification: Rotation error

[TaranMeyer]

Description
Seeds mis-id'd when oriented vertically

Expected behavior
Seed is correctly ID'd as Bromus hordaceus

Actual Behavior
Seeds were ID'd as Bromus secalinus (incorrect ID), with confidence values ranging from 51 to 87 %. An additional ID as Ambrosia trifida was given at 50% confidence; Correct ID (Bromus hordaceous) was given at 37% for one of the seeds. When I downloaded the image and rotated it 90 degrees, correct IDs were returned between 84-96%.

I repeated the exercise with the same seeds on a white paper background and got even more extreme results:


(Same settings as earlier images in this case)

Repeat the process with Swin Transformer. Detect the right seed, but hallucinate a fourth one.
