A research group led by Professor Hiroshi Ishikawa and Junior Researchers Satoshi Iizuka and Edgar Simo-Serra of the Faculty of Science and Engineering at Waseda University established a technique for automatically colorizing grayscale images by using convolutional neural networks, a type of deep learning by artificial intelligence.
The colorization architecture of this model is divided into four parts: a low-level features network, a mid-level features network, a global features network, and a colorization network. This colorization method differs from previous ones for it is completely automatic and does not require any reference images.
This technique, partially supported by Japan Science and Technology CREST Program, will allow natural coloring of different kinds of images, including monochrome photographs dating back 100 years. The results of this research will be presented at an international computer graphics convention, SIGGRAPH 2016, in Los Angeles in July.
