I'm not a HN etiquette stickler, and I'm not accusing anyone of any foul play, but the actual YouTube video was submitted 17 hours prior to this post: https://news.ycombinator.com/item?id=6358080 This is just in case you want to throw a few upvotes their way for being first. This also illustrates that late night (PDT/UTC -8) posts don't get a whole lot of votes and proper timing is crucial to getting lots of votes.

It was also submitted here even earlier: https://news.ycombinator.com/item?id=6351712 Personally, I'm just glad to see this video finally getting traction. It really is such a cool demo. It even stands out in the field of consistently high-quality SIGGRAPH demos. Can't wait to read the paper!

I submitted it too https://news.ycombinator.com/item?id=6352371

It's weird that it has received quite a few votes each time and never made it to the front page. Was it a timing issue (late night, early morning, non-American hours) or is YouTube "weighted down" somehow?

A lot of cool rendering/modeling research seems amazingly well-suited for the film industry and this is a perfect example ... besides the obvious applications in making CGI versions of real-world scenes, you can just imagine the director saying "oh no, that lamp is in the wrong location in all that footage... move it (without reshooting)!"

I wonder if it's just a coincidence, or whether the mega-bucketloads of money the film industry throws at CGI are a major factor in funding related research even in academia?

Also awesome is that it handles the background replacement so well. This could also be used to just remove an ugly lamp post, telephone pole, etc from an otherwise good photo. (assuming you can remove objects and resave the image) Edit: I am aware that Photoshop has some of this available. I've not played with it so I don't know how they compare.

The video says they used the PatchMatch algorithm for the background fill, and a quick search reveals that PatchMatch was developed in 2009 in association with Adobe and later incorporated into Photoshop CS5.

Wow, super impressive. And meanwhile, Silicon Valley is working on the gazillionth social photo sharing app.

The other side of the argument is that social networks improve far more lives than academic research projects like this.

Without social networks like Reddit or HN I would have been unlikely to ever see most of the academic research that I do come across, like this!

Is there a reason many of these crazy image processing technologies never seem to have actual demos or releases? The only exception I can think of it the "smart erase" idea, which has been implemented in Photoshop as well as Gimp.

Photoshop has added, and is regularly adding more, features based on similar technologies. An example of a content-aware featuree: http://www.youtube.com/watch?v=D58CG_-AWnY

Is it too much to hope that this tech will be implemented in a program that's within an "average" user's budget? (i.e. non-enterprise).

WOW.

Forget the Photoshop stuff, this needs to be integrated with 3D printing immediately.

Spit out a design file into Tinkercad[1] for some minor adjustments and BAM, you've made a printable 3D model.

I want this + i❤sketch now, but unfortunately I suspect that jumping up and down and shouting isn't likely to help. http://www.dgp.toronto.edu/~shbae/ilovesketch.htm

Thanks for the reference. Are you aware of any (commercially available) handdrawing to CAD software? I need to do a bunch of relatively simple figures for my thesis, and it would be much easier if I could just use handdrawings and than transform them to professionaly looking figures.

Have you tried Google SketchUp? It might be the closest thing to this type of ease-of-use that I've seen so far, and it's free.

This indeed is very impressing and I see the how much work passion is into this project.But I still have to say it almost only about round or cylindrical objects, there is still a long way to go

He did a couple rectangle ones too. And it's cylindrical tool handles a lot more than cylinders.

Question for the entrepreneurs: how would one monetize such a cool algorithm? I come across plenty of cool stuff like this, but without any idea how they can solve real problems.

Software for use with 3d printers. Modeling stuff for printing is really hard right now, definitely a big barrier.
