This is really cool! Since you have experience with image manipulation using machine learning I’d love to get your advice for a project I want to start. I have a little business that sells 3D printed jewelry (https://lulimjewelry.com https://lulimjewelry.com). My biggest seller is customers engraving their or their loved ones fingerprint on the ring. Most of those prints come in needing manual cleanup, which I can usually do in a few minutes. I’d love to train a ML algorithm to do this, and I’ve been building up the before and after pictures over time using my manually cleaned up customer fingerprint images. Can you give me suggestions or pointers on the sort of algorithm that may be best suited for this task? Just something to get me started down the correct path would be very helpful. Also, would you have a rough estimate on what a good number of training images would be? I want to know if I’m currently in the ballpark or if I need to create a ton more.

I personally don't have any experience with this but just thought I would share what I found while researching this. Not sure about using ML algorithm but you could look into “edge enhancement”. I think edge enhancement combined with a bit of tweaking of contrast, sharpness should give you good results. Sharpening Filters is another one to look at. If you are looking to do this in an app, GPUImage library has sharpening filters. It might have edge enhancement filters too though I am not 100% certain. Search for “edge enhancement online” for example for some tools. You can also look for their algorithms too. Photoshop and Photopea probably do them too. Here’s some example I tested with an online image with edge enhancement. Your customers probably give you better quality and size images than this: Using this tool: https://pinetools.com/image-edge-enhancement https://pinetools.com/image-edge-enhancement Uploading this image: https://listverse-wpengine.netdna-ssl.com/wp-content/uploads/2019/06/4a-fingerprints-922820626.jpg https://listverse-wpengine.netdna-ssl.com/wp-content/uploads... gives this result: https://i.imgur.com/3TvSVGU.png https://i.imgur.com/3TvSVGU.png
