outlines randomly modified

[raynernunez]

Hi, I'm trying to compare these outlines, Lepidoptera genitalia, but for some reason momocs gets wrong, and randomly, some of the images. I removed part of the structure in some samples to compare and the outlines were captured fine, look at the two marked samples. I ran it several times, each time different outlines were modified. Maybe these shapes are too complex? Any help would be great. Thanks.

Hi there, I don't think that's a matter of shape complexity but how the masks were done. The current algorithm is only fully reproducible when the masks are on the middle point of the jpg. If not, the algo will try to find a black pixel, randomly, on the jpg. Also when single pixels are isolated on the diagonal eg the top right 'x' below: ``` x o x x x o x o o ``` outline extract may/will fail hope this helps, if not, send me the masks that produce different outlines and I gonna have a look, all the best, v Le lun. 24 juin 2024 à 10:59, raynernunez ***@***.***> a écrit :

I'll check that, thank you very much

Hi, when I created the mask I cropped them at the same size and tried them to be at the center. Now I tried adding a bit more white background around the shapes but it is still happening and each time I run it gets erroneous outlines for different samples (attached 2 examples). Here are the masks so you can try to figure out how to make it work.
