Doodling is fun. You’ll be hard put to find a student who hasn’t decorated his or her copy with some line art, be it random criss-cross or a hyper-realistic drawing of the professor.
On the other hand, not as many people like to color the pieces of art they have created. So, what if there was a software that could do it for you?
Meet the PaintsChainer, a simple online tool that can take your piece of line art and then automatically color it in a water color-like style. The drawing can be created using any program you choose.
Since it also accepts drawings in the JPG or PNG format, you can simply take and upload of a doodle drawn on paper. The results would be somewhat poor when compared to something drawn on a computer drawing program, but I was still pretty impressed. You can also tweak the tool to give you much better results by telling it which color to use, where to apply them, etc.
Below, is a picture of a sketch of Iron Man I made a couple of years ago, before and after using PostChainer. You can create your own by heading over to PaintsChainer.
How does it work?
PaintsChainer uses a flexible neural network framework to automatically colorize your photos. Neural network is a form of artificial intelligence, loosely based on the workings of a human brain and how it solves problems with large clusters of biological neurons connected by axons.
