Alas, I can find no build instructions. How does one build this on Linux? (I have cmake, OpenCV and wxwidgets installed.)

This looks really interesting. I could see a business here of taking photographs and turning them into coloring books.

Someone beat you too it, unfortunately: https://www.reallycolor.com/

I wonder if given the input and output of the algorithm, you could train some type of deep neural net. And if successful, what the hidden layers would look like?

Nice Wxwidgets!

Maybe I'm missing something, but frankly I think if you're building GUI with Python, tkinter is probably the best option. Comes with stock, is pretty solid, and on edge-cases serves you well.

I had to create some applications with py earlier this year, I started out with pyside but it was really heavy and kind of difficult to grok. wxwidgets I tried as well and it didn't work (I needed mouse cursor information and use it in a certain way to draw certain things, it was messy to do it with everything except tkinter).

I would love this as a linocut. I want to duplicate to look that some books use on their cover.

Cool. Could it be also used on video without flickering ?

No, I don't see any reason that this would avoid flickering. The method is chaotic and processes a 2D image, not a 3D image-time volume.

Thanks; worked like a charm once I pulled in some more libraries. One thing to tweak for Linux use: add upper-case versions of the image file extensions to the fifth parameter of the openFileDialog call in gui.cpp, so you don't have to rename all those image files that cameras and phones tend to give upper case names to.
