Neat! This uses Structure from Motion to compute depth to each pixel and correct backscatter for the specific distance light is traveling from the subject. Typical flat color correction algorithms can help reduce the blue tint typical of underwater photography, but it's only physically correct for a narrow distance band.
- perf1 7y agoModern Image programs have a Dehaze algorithm that already can calculate a depth map using the haze. Wonder if this is better.
- Double_a_92 7y agoThe paper says that they used current dehazing algorithms as a base, and added more parameters to them.
- dorkwood 7y agoWhich programs? I had to generate some depth maps recently and couldn’t find a good solution.
- bufferoverflow 7y agoThat's not what the comment above said. They said some imaging programs create depth maps, and process images based on that. It doesn't mean it creates a depth map for the user, it can simply be an internal part of the whole process. Photoshop RAW pluging does dehazing. I don't know how it works.
