Sharkbook - using the MiewID algorithm
As we know, MiewID has better results than previous Groth and i3S algorithms. So I have been running a review of every shark individual and re-testing the images using the MiewID algorithm to see if each individual shark is indeed an individual. So far, after re-revieweing over 70% of sharks I have found that 16% of sharks were in fact not unique afterall.
However, today I kept finding unusual results and think this is a bug within MiewID.
I have found situations where one image has been uploaded twice at different times. Image A is Image B. Yet when I run results on Image A it does not return Image B in the top results. But when I run results on Image B it finds Image A right away and returns it as its top result.
If Image A and Image B are exactly the same - why wouldnt both search results return each other as the best match? Why is it only occurring in one direction?
Here are some examples:
Example 1, where Image A does not return Image B in the results, but Image B returns it straight away:
Image A: Sharkbook: Wildbook for Sharks
Image B: Sharkbook: Wildbook for Sharks
Example 2, where Image A does not return Image B in the results, but Image B returns it straight away:
Image A: Sharkbook: Wildbook for Sharks
Image B: Sharkbook: Wildbook for Sharks
Example 3, where Image A does not return Image B in the results, but Image B returns it straight away:
Image A: Sharkbook: Wildbook for Sharks
Image B: Sharkbook: Wildbook for Sharks
This bug is truly puzzling me as I have found it frequently and it makes me fear that the algorithm is not reviewing all images or something. Please can you investigate and let me know what you find?
