je ne pense pas que c’est aussi simple que ça ...
faut voir la vidéo où elle explique comment elle fait ; ça nécessite plein de prises de photos à diverses distances
One caveat is that the process requires distance information to work. Akkaynak takes numerous photographs of the same scene from various angles, which Sea-thru uses to estimate the distance between the camera and objects in the scene—and, in turn, the water’s light-attenuating impact. Luckily, many scientists already capture distance information in image data sets by using a process called photogrammetry, and Akkaynak says the program will readily work on those photographs.
The algorithm differs from applications such as Photoshop, with which users can artificially enhance underwater images by uniformly pumping up reds or yellows. “What I like about this approach is that it’s really about obtaining true colors,” says Pim Bongaerts, a coral biologist at the California Academy of Sciences. “Getting true color could really help us get a lot more worth out of our current data sets.
