Colorized movies with neural network

I colorized some black and white movies using the trained neural network model from Zhang et al.

The movies were converted to single frames via ffmpeg, colorized and then put together. As you will see this creates a lot of changes from frame to frame and could be improved by some persistence parameters for scenes. The scripting was done in python using the example from https://github.com/richzhang/colorization. The neural network is implemented in caffe.
