The repository contains 152 videoclips (including 54 test videos and 98 training videos) at different spatial and temporal resolutions, showing different scenes (different cameras, changes of viewpoints, etc..) under different conditions.
In real-life underwater scene, often video quality is compromised by:
- the presence of algae on camera lens (due to the direct contact of seawater with the lens);
- encoding problems due to transmission bandwidth limit;
- atmospheric phenomena (e.g. typhoon), that may displace or disconnect the cameras resulting either in black videos or in recording scenes of no interest.
