Datasets

Datasets are important for evaluating and validating a method. The lack of standard datasets hinders the fair evaluation.

List of datasets commonly appear in underwater literatures.

Dataset	Size (number of images)	Description
U45	45	Collection of 45 images commonly used in literature, all images are resized to 256x256.
EVUP	6,665	Images of "good" and "bad" quality annotated by 6 participants.
UIEB	890	Reference of underwater images collected via subjective experiments.
RUIE	3,630 (UIQS), 300 (UCCS, UHTS)	Contains 3 subsets grouped by colour cast and image quality (determined by UCIQE by Yang and Sowmya.).
SQUID	57	Images captured by stereo cameras with colour charts placed in the scene.
Sea-thru	1,157	Images captured by stereo cameras with colour charts placed in the scene.
TURBID	112	Contains 5 subsets of scenes captured in a water tank, with degradations synthesised by chemical reagents.
