intensely cool. very useful for re-purposing icons whose backgrounds would otherwise clash with a website's color theme.

Yeah, it actually works really well on vector art. If you're into that sort of thing, check out the sick bg color removal and alpha channel "recovery" by zooming way in on the boundaries.

Really nice. First time I tried it I carefully shaded the red and green areas and it worked ok. After looking through the comments here though I clicked green once on the part I wanted to save and then 3-5 red clicks in other areas and it worked flawlessly. Great job.

Yeah, we need to figure out a way to get people to do the first time what you did the second time...

Seems that the same tech could be reapplied to giving depth of feel to images by giving an option to unfocus the background instead of just deleting it.

Filters could also be a consideration for future (ie. popular things like black and white background with a color foreground)

Is anyone else getting an error? "Network Error We are having trouble connecting to the server. The following tasks have been unable to complete: Connecting to worker "Unable to connect to the worker." Waiting" This is occurring after I drag and drop an image

Sorry, that's me being slow scaling out the backend. I've added a couple more boxes. (Haven't added auto-scaling yet)

I first thought that there is still the same problem but then I saw that the web socket worker is using 9006. Our company network is blocking unusual ports. Any chance to move that to 80, 443 or 8080?

I actually wrote my honours thesis on this topic. In academia it's called Alpha Matting/Image Matting. There's a great website http://alphamatting.com/ that provides a benchmark dataset and a comparison of a lot of influential methods. I applaud your work in making a real time and interactive matting algorithm! One day it might be also as accurate as state of the art methods. You guys should write a paper about your…

(I'm one of the devs.) Thanks for the link! Real time is a pretty big constraint, and the input for those results is a much more complete labeling than we expect (only 22 to 44 pixels around the ground truth boundary are left uncertain). But I'll definitely read the paper and hopefully we can gain some insights from it!

Actually Shared Matting is far more applicable than KNN Matting. It's designed for real time use and has a post processing step which will help you deal with fine detail like hair.
