Description Foreign body contamination in food is one of the major sources of complaints against food manufacturers, and can lead to injury, loss of brand loyalty and large recall expenses. Different technologies, such as X-ray or infrared techniques, are currently applied to detection systems used for food inspection, but physical contamination, with e.g. wood, plastic, metal and glass, is still present in food.

The main objective of this Master Thesis is to investigate the use of machine learning techniques to identify contaminated food products along the packaging line. The input data are measured via a custom microwave system placed on a testing packaging line available at the antenna and EMC lab, DET. Depending on the background of the Candidate, the acceleration of the selected ML algorithms with software or dedicated hardware design methods will be considered in the Thesis.
