Introduction

When I see a historical black and white photo, I always wonder what was the real color, what did the photographer see when taking the photo.

It is not easy to discover the exact color of the B&W photos, but it is possible to colorize the photo based on experience and imagination. It can be done by investigating the possible colors of the objects in the photos, for example, color of cloths, building, trees, cars, etc., and colorized them manually using some software such as Photoshop.

The other approach is to train the computer to understand the colors of different objects by providing a large of amount color photos, then ask the computer to colorize by identifying plausible color for the detected objection. Thanks to the development of deep learning, it can be done by using Generative Adversarial Network (GAN).
