Following the setup of previous works [8, 16], we conducted experiments on various bit image restoration tasks.

We utilized a dataset of 2000 16-bit images, with training

data sourced from SINTEL [37] and FIVE-K [38]. SINTEL

is an animated short film dataset containing over 20,000 16-

bit lossless images with a resolution of 436 × 1024 pixels. In

FIVE-K, randomly select images from 5,000 16-bit natural

images for the experiment.The test set includes 8 images

randomly chosen from the SINTEL dataset (referred to as
