image size limit?

[taimansulimani]

Hello, thanks for this, it's very useful.

I'm having a problem analysing this folder where I have 512x512px transparent .pngs where only 576px are black. The black pixels that form my paths should be different in every image but difPY says they are all the same, see output attached. I tried setting similarity to low but no luck. Are my images too small or maybe the differences are too subtle? Is there anything I'm missing here?

Thanks for your help

solved by increasing image size and adding solid background
