The art and science behind auto-enhance for iOS
Dec 17, 2014

Summary
This post details the development of an auto-enhance filter for iOS, which uses computational imaging techniques (Global Tone Mapping, Local Tone Mapping, and Noise Suppression) to improve image quality by mimicking human visual perception and darkroom photography techniques. It explains the challenges of dynamic range, image memory, and noise in digital photography and how these algorithms address them.
