Deep Learning Restores Time-Ravaged Photos

Researchers have devised a novel deep learning approach to repairing the damage suffered by old photographic prints. The project is open source and a PyTorch implementation is downloadable from GitHub. There’s also a Colab where you can try it out.

We’ve encountered neural networks that can colorize old black and white shots, can improve on photographs of landscapes and even paint portraits in the style of an old master. Here the goal is more modest – to apply a deep learning approach to restoring old photos that have suffered severe degradation.

The researchers, from Microsoft Research Asia in Beijing, China and at the University of Science and Technology of China, and now the City University of Hong Kong start from the premise that:

Photos are taken to freeze the happy moments that otherwise gone. Even though time goes by, one can still evoke memories of the past by viewing them. Nonetheless, old photo prints deteriorate when kept in poor environmental condition, which causes the valuable photo content permanently damaged.

As manual retouching of prints is laborious and time-consuming they set out to design automatic algorithms that can instantly repair old photos for those who wish to bring them back to life. 

The researchers presented their work as an oral presentation at CVPR 2020, held virtually in JuneĀ  and their paper, “Bringing Old Photos Back to Life”, which is part of the conference proceedings is already available.
