This Hotpot AI service analyzes black and white pictures and turns them into realistic color photos. To do this, we built off the wonderful DeOldify project and applied proprietary advancements based on the latest techniques in deep learning, a subfield of machine learning.
The outcome is a sophisticated prediction about the colors of the people and objects in a picture, but like any prediction, it could be wrong or biased. For instance, our AI might colorize a shirt blue when it was actually red.
For this service, pictures are not saved without user permission. For storage costs and user privacy, we only retain images for as long as necessary to run our machine learning models, and do not store photos beyond this.
