How to Find Duplicates in Line Drawings and Finished Artworks

[1235789gzy1]

I have a picture of different stages of my artwork from draft to finished product, and I hope to find them and ultimately delete any unnecessary drafts



If these three images have different resolutions and some displacement (differences in distances from the image subject to the image edges), how can duplicates be found? Perhaps 'line feature matching' can be used to address this situation?

Were the existing similarity methods were not effective in your case?

Yes, even if the similarity is adjusted to the lowest 50%, it still cannot match these three images
