AdaInt: Learning Adaptive Intervals for 3D Lookup Tables in Real‑time Image Enhancement

AdaInt introduces a lightweight convolutional network that predicts non‑uniform sampling coordinates and basis 3D LUTs, using a differentiable binary‑search AiLUT‑Transform to enable end‑to‑end training, thereby delivering superior PSNR, negligible extra parameters, and real‑time color enhancement on ultra‑high‑resolution images, outperforming prior state‑of‑the‑art methods.
