Simple Image Vectorization
- tomcam 6y agoBeautifully written and illustrated. Makes the algorithm clear and seems to give everything you'd need to implement it (afraid to test this assumption because I'm afraid it would be too much fun, and I have deadlines ;)
- k82a 6y agoHad to think of the paper about depixelizing pixel art, fun stuff if you're interested: https://johanneskopf.de/publications/pixelart/paper/pixel.pdf https://johanneskopf.de/publications/pixelart/paper/pixel.pd...
- srgpqt 6y agoI think this is the first time I read a paper that includes real code and even links to a github repo. Amazing.
- Waterluvian 6y agoI have badly needed vectorization tools for client side geomatics work. But I haven't found anything that works in thr browser. Going to have to check out the examples here but if anyone wants to make a client side library around it, I think there's demand!

- chris2y3 6y agoIt's indeed a very good read! I have done a similar thing, with a completely different approach, because my math is too bad. https://github.com/visioncortex/vtracer https://github.com/visioncortex/vtracer
- mthoms 6y agoIt works quite well actually. Nice work.
- yig 6y agoThe site is full of great interactive explanations. Nice work!
- tzumaoli 6y agoCheck out our recent work on improving image vectorization using gradient descent: https://people.csail.mit.edu/tzumao/diffvg/ https://people.csail.mit.edu/tzumao/diffvg/
- zzleeper 6y agoThose figures look amazing! Also, its crazy how many things can be improved by a clever use of gradient descent

- legulere 6y agoNot having looked at vectorization so far I wondered if some ideas from CT reconstruction can be applied to image vectorization. In both cases you start with a base image that is projected on one (or in the case of tomography several) pictures. The goal is to retrieve the original. https://en.m.wikipedia.org/wiki/Tomographic_reconstruction https://en.m.wikipedia.org/wiki/Tomographic_reconstruction
