Trends in application of imaging technologies to inspection of fish and fish products

Applications of imaging technologies are playing an important role in several major areas in research and industry, including process optimization, automated sorting and grading, and automated processing. This review looks at the trends in application of imaging technologies to inspection of fish and fish products – in particular reviewing the applications of VIS/NIR imaging, VIS/NIR imaging spectroscopy, planar and computed tomography (CT) X-ray imaging, and magnetic resonance imaging (MRI). In recent years, a large amount of research has been published on the use of imaging technologies for inspecting fish and fish products. This review article condenses a representative selection of recent research and industrial solutions in order to observe the general trends in how the imaging technologies are applied to inspection of fish and fish products. Based on these observed trends, we provide some viewpoints on the current situation and suggestions for future research directions.
