The art and science behind auto-enhance for iOS

What this post added

Introduced an auto-enhance filter for iOS that leverages computational imaging techniques: Global Tone Mapping (GTM) to adjust overall image tone and dynamic range, Local Tone Mapping (LTM) with edge-aware masks to adapt local contrast and prevent haloing, and Noise Suppression (NS) to reduce noise in flat regions. These algorithms are designed to mimic human visual perception and historical darkroom techniques to improve image vibrancy and detail.
