Sea-thru works on RAW images or videos taken under natural light.

​​

The distance (D) information can come from any source, e.g., structure-from-motion from multiple images, stereo image pair, specialized sensors, etc.

​

​Sea-thru is a physics-based algorithm using the Akkaynak-Treibitz underwater image formation model (CVPR 2018). It does not use neural networks and was not trained on any dataset. It works without a color chart, or any information about the optical qualities or depth of the water body.

​
