Real Time Machine Vision System for Quality Assurance of Canned Tuna
نویسندگان
چکیده
We describe a PC-based real time machine vision system for the quality assurance of canned tuna at a tin rate over 1,000 tins per minute, allowing the inspection of the tin and its contents, with two main purposes: preventing defective tins from damaging the closure equipment or from reaching the market with a defective closure, and deviating from the production line tins with low quality content: bruised or darkened areas, excessive percentage of crumb, presence of strange bodies, or partially filled tins, such that they may be fixed and reintroduced in the line without wasting any oil or sauce. The system comprises a iPentium PC with frame grabber, a greyscale line scan CCD camera, a fibre optic halogen lighting system, and a compressed air system for the deviation of the rejected tins, and has been entirely programmed in C++.

متن کاملBiogenic Amines Content of Canned Tuna Fish Marketed in Iran
Canned tuna fish are frequently and largely produced and consumed in Iran and also exported. Therefore, their biogenic amines content should be of some concern to human health. In the present study, the levels of histamine, putrescine, tyramine and spermidine in 40 samples of canned tuna fish were determined. Histamine, as the major chemical hazard of seafood products, was detected in 57.5 % of...
