Images taken by underwater cameras are frequently of a comparatively low quality: falsified colors, distortions, and significantly lower contrasts characterize these images. The reasons are special properties of water, resulting particularly in the dampening, diffusion, and refraction of light.
The researchers of Fraunhofer IGD are intensively pursuing this demanding subdomain of image processing. They have developed a comprehensive solution kit, providing highly efficient processing in customer projects. Some of the procedures are real-time-capable and can assist the operator in controlling remotely operated vehicles (ROVs), for instance. These algorithms were also successfully ported to an embedded system. Image enhancement can thus be integrated directly in underwater cameras.
