PLYMOUTH MARINE LABORATORY

A team of scientists from Plymouth

Marine Laboratory have ‘trained’ an Ar- ti? cial Intelligence (AI) model to recog- nize and classify the different types of marine plastic captured in images shot by a video camera mounted on the side of a boat. Funded by the PML internal research program and the European TRITECH INTERNATIONAL Institute’s Sea Ice Prediction Network
