PICO: A Practical Learned Image Codec Optimized for Human Visual Perception
By
ksec
Toasted to a respectable shade. No regrets, no crumbs left.
Summary
The article introduces PICO (Perceptual Image Codec), a learned image compression codec optimized for the human visual system. It was developed through a comprehensive study of modeling choices and millions of model configurations, jointly optimizing for perceptual quality and on-device runtime. Based on large-scale subjective user studies, PICO achieves 2.3-3× bitrate savings compared to traditional codecs like AV1, AV2, VVC, ECM, and JPEG-AI, with an additional 20-40% bitrate savings.
