Fish Inspection System Using a Parallel Neural Network Chip and the Image Knowledge Builder Application

Fleet owners are very interested in filling their boats as fast as possible with the fewest and most qualified personnel, thus reserving maximum occupancy for their refrigerated storage. During an expedition, which can last between one to two weeks, the fish processing machinery operates around the clock (figure 1). Typically, fishes are brought on the boat and dropped into metal pockets that convey them through cleaning, cutting, and filleting machines. Anomalies, which must be detected at the beginning of the chain, include a fish of the wrong species or a damaged fish. Such anomalies must be rejected immediately.
