What Wildbook are you working in?
Grouper Spotter

What is the entire URL out of the browser, exactly where the error occurred?

Can you describe what the issue is you’re experiencing?

Can you provide steps on how to reproduce what you’re experiencing?
After matching process, results page shows high values for comparisons between images. However, the background is being matched more than the grouper themselves

If this is a bulk import report, send the spreadsheet to services@wildme.org with the email subject line matching your bug report

Hi @BTran

HotSpotter considers all the pixels in the bounding box, and where these almost exactly correspond (many of these shots appear to have elements of the same background) it will produce a generally low score false positive like this. There are various strategies we employ for reducing this (e.g., background subtraction), but where these elements atre truly exact between images and tight to the body, they will still popup.

Thanks,
Jason
