Evidence claims:
- [upstream_claim] README: learns image-adaptive 3D LUTs for high-performance photo enhancement in real time; provides the FiveK dataset resized to 480p (8-bit sRGB, 16-bit XYZ inputs, 8-bit sRGB targets); full datasets over 300 GB; model trained at 480p applies to 4K or higher without performance drop. · locator: README, Downloads and notes · source: https://github.com/HuiZeng/Image-Adaptive-3DLUT
- [sourced_fact] GitHub metadata: Apache-2.0, not archived, last push 2023-12-16. · locator: repository metadata · source: https://github.com/HuiZeng/Image-Adaptive-3DLUT
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
