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!

Earlier quoted context omitted.

I copied the marks in the example and besides needing to tell it to include the cream color under the strap, it worked exactly as shown on the homepage, so maybe just add that extra red there in the example. Unfortunately it is freezing up on me using an image with a gradient at about 90% of the initialization.

Yeah, we're getting some null pointers in the worker. Not entirely clear why that's happening (it of course wasn't happening an hour ago...). I think I stuck a race condition in there somewhere and it's getting exposed for the first time. Please try uploading the image again :-/
