Sea-thru Brings Clarity to Underwater Photos
November 13, 2019 4:44 PM Subscribe
Photographing coral reefs is difficult because even shallow water selectively absorbs and scatters light at different wavelengths, washing out colors. This makes it difficult to use computer vision and machine-learning algorithms to identify, count and classify species in underwater images. But a new algorithm called Sea-thru, developed by engineer and oceanographer Derya Akkaynak, removes the visual distortion caused by water from an image. The effects could be far-reaching for biologists who need to see true colors underneath the surface.
