What Wildbook are you working in?
Amphibian and Reptile Wildbook
What is the entire URL out of the browser, exactly where the error occurred?

Can you describe what the issue is you’re experiencing?
Very high frequency of “Image Analysis has returned and no match was found.” despite high number of encounters in the project.
Can you provide steps on how to reproduce what you’re experiencing?
I have uploaded ~160 photos of adult fire salamanders to the project “Uni Bielefeld - Adults Kottenforst” using the bulk upload. I sent those pictures to identification against all locations (not just Kottenforst). When checking the matching results, I almost exclusively got: “Image Analysis has returned and no match was found.”. I find this suspicious snce the project now has 464 encounters but still there were only very few possible matches suggested. Is this correct or is there a problem with the AI or the image quality?
If this is a bulk import report, send the spreadsheet to services@wildme.org with the email subject line matching your bug report
Done.

Hi @Max.Muehlenhaupt

This is a valid result. HotSpotter considered 2405 potential matches and ruled all of them out as unlikely matches. There was no score above 0. Unless it truly missed a match, this is HotSpotter indicating no potential matches and not wasting your time with false positives.

Thanks,
Jason

Hi @jason ,
thank you for your response. My colleague @Pia uploaded ~50 photos in March. In only 4 cases, she received the message “Image Analysis has returned and no match was found.” .
However, in my case, I got this message for almost every encounter out of 160. This got me wondering if there’s something wrong with either my photos (however, they do not look much different to Pia’s) or the matching AI.
