What happened?
i tried to match fire salamander adults. the software recognised the background (numbers) but not the animal https://tier2.dyn.wildme.io:5001/api/query/graph/match/thumb/?extern_reference=rxcxtizlslkrvmsx&query_annot_uuid=d56dd30d-6521-4cfa-873b-1d91e3acf8c5&database_annot_uuid=d614b012-ddb0-425f-94b5-77d05874600e&version=heatmask

@Drew @parham is this a problem that background subtraction could solve?

Not that close to the body. This is why we discourage uniform backgrounds generally. This is normal HotSpotter behavior.

To add another data point, background subtraction will not completely eliminate a very strong background match, it simply makes it less confident. A strong background match (like the pixels of a black printed character 2 on a white background) can still sometimes outweigh a weak foreground match, even with background subtraction working perfectly.

As @jason said, this is normal HotSpotter behavior and hard to suppress without making the overall system less accurate.
