It's "not a photoshop" in that it's not someone manipulating the image until it looks good. It's an algorithm that (according to the video) uses precise physical modeling to achieve the correct color, regardless of aesthetic preferences.
- mieses 7y agodoes the method construct some model of the physical environment or does it just modify the color of each pixel based on the color chart (color calibration/correction)?
- DougBTX 7y ago> 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. https://www.deryaakkaynak.com/sea-thru https://www.deryaakkaynak.com/sea-thru
