Wrong images matched?

I haven't fully read how it is implemented but I assume these images shouldn't be similar?

It is just a small chunk of a single cluster. That cluster treats 1k+ images as similar

I suspect these images have identical but incorrect EXIF thumbnails. To see the thumbnails, use the Jpeg thumbnail reader: https://vitali-fedulov.github.io/similar.pictures/jpeg-thumbnail-reader.html

Try to run image clustering with disabled box "Option to accelerate the search" and let me know. When the option is disabled, images are fully read, and the results should be as expected.

I tried it and it does not show some images

Jpeg thumbnail reader?

[kapitanluffy]

Jpeg thumbnail reader?

Yep

[vitali-fedulov]

Correct. Jpeg thumbnail reader uses a very simple EXIF reading algorithm. For some images it does not work. I am not planning to fix it, as it is not commonly used, if at all.

In relation to your initial comment - have you tried clustering with disabled box "Option to accelerate the search"? Did it work correctly?

[kapitanluffy]

Yes I tried that also. I think I know the problem now. Maybe because there's an all-black image. Here's a small sample of images that were grouped as similar
