autocolorize

Automatically colorize images using Machine Learning.

• Project page <http://people.cs.uchicago.edu/~larsson/colorization/>__
• ECCV 2016 paper (arXiv <http://arxiv.org/abs/1603.06668>__)

Installation

Make sure that you have Caffe (with Python bindings). Then run::

pip install autocolorize

Run::

autocolorize grayscale.png -o colorized.png

API

You can also colorize from Python (assuming grayscale is the image that you want to colorize)::

import autocolorize
classifier = autocolorize.load_default_classifier()
rgb = autocolorize.colorize(grayscale, classifier=classifier)

Sparse training

We provide custom layers for doing sparse hypercolumn training in both Caffe (see caffe/) and Tensorflow (see tensorflow/). This can be used for other image-to-image tasks, such as semantic segmentation or edge prediction.

Look inside the train folder if you want to train from scratch.
