Spotting Fish Bones in Cod Fillets
Norut IT and Fiskeriforskning have developed a method for spotting fish bones hiding in cod fillets. The first robots for plucking out the tricky last bones will soon be installed in Norwegian fish industry. This may nearly double productivity and once again make our fish processing competitive with China.
The secret is to use x-ray imagery and extremely efficient image processing which gives
the answer “Bone” or “No Bone” in a matter of milliseconds. The actual bone plucking is done mechanically followed by a final control. The researchers at Norut IT are experts in Remote Sensing and will ordinarily analyse satellite images to obtain information about phenomena on the surface of the Earth. It turns out that pattern recognition in satellite images and in x-ray images can be done using the same priciples.
