I decided to challenge it a bit with this one: Here's what I got: Not perfect, but OK, that was admittedly a tricky one. So I tried taking that image it made and running that through, but it produced the same result again. So I cropped down the original image to just one side of the coin, and got a slightly better but still imperfect result: Guess that text background was just too tricky for it, but I'm still impressed. (I should add that it worked just fine for me with simpler backgrounds, however- despite some annoyance with the captchas.)
Did I miss where you tell it what size you want? I tried a couple of pictures and it worked well but the output size was tiny compared to the originals... much too small for the service to be useful to me.
'In hand' photos are the hardest to remove backgrounds. Try shooting it on a neutral background (I use grey). You can put the coin on a translucent surface (a plastic food container works very well) with a piece of paper underneath. Works very well.
@TIF If you go to the pricing page at https://www.remove.bg/pricing it says the free version goes to 1/4 megapixel, ie 625x400. But if you sign up for one of the plans, you'll be able to use your "credits" to choose among HD (4 megapixels), 4k (10 megapixels), or 'medium' (1.5 megapixels). Took me a few minutes to process all that too! Bottom line is, for my needs, I could probably sign up for the Basic plan for a couple months, photograph my entire collection, then downgrade to the lowest plan for new coins that I may add in a given month.
Is this the Ken Dorney trick you're referring to? https://www.cointalk.com/threads/testing-out-new-macro-lens-looking-for-feedback.329058/page-3 Very interesting! I'm pleased to add that one to my bag of tricks.
Oh. Thanks for that link! I think I'll continue to remove the backgrounds in Photoshop Elements. I don't need another monthly bill. It is very tempting though...
Not all heroes wear capes, @Archilochus Unless you wear a cape... Took a hasty photo to see how it would do with blurred edges on a muted background w/ texture. It didn't have an issue. My only complaint is resolution. Wish we could go a little bit bigger; but this is a phenomenal time saver. -Michael Edit - Have to pay for higher res. Makes sense
I tried the background removal on a Chinese carved cinnabar lacquer dish measuring 4.0 in. dia. successfully without editing , but the reduction in size is annoying . I can't justify spending the money for a premium upgrade . The removal tool also worked well on this Costa Rican Pre-Columbian axegod pendant 6 3/4 in. long. Again, the size reduction is annoying .
I tried a couple: Before After Before After A bit of an artifact at the top of the obverse, and at 3:00 of the reverse, but they should be easy to clean up. Not bad for less than one minute's work.
I must say that for my purposes this app is really worth the time it takes to adapt it to my needs. Hardly any. Thank you. Here is a before and an after: Before: black background only (Sabina): After: coin superimposed on image of sculptured bust: THANK YOU for the link.
It doesn't have to be if your image editor has the right features. In Photoshop you can resize the image by several methods, some of which preserve the original acutance without serious alteration of the pixels. For my pic of the coin over a bust, the original of the bust was rendered at 79 dpi. I changed it to 600 and resized the final to a 900 pixel height. It came out clean and was significantly larger.
I haven't had a chance to try it yet. It should be possible to open the small cleaned image and select the background color. (In GIMP I would use the magic wand for this). Then convert the selection into a mask and apply it to the original image.
