In recent years, this has materialized through problems with the importation of Norwegian salted and rockfish products to Brazil. Visible dirt will not be accepted. This poses a major challenge for the industry, both for salted fish, cuttlefish and fillet producers. Ideally, the cyst should be detectable already in gutted fish, but this is a bigger challenge than detecting visible cyst in fillets, spotted fish, salted fish and rockfish. In previous projects requirements for detection have been measured against all nematods in the fish, both visible and non-visible. This has proven difficult to achieve with a sufficient detection rate. In the attempt to approach the desired detection rate, the number of false positives has also become too high. When only visible cracks are to be detected, this can simplify the solution. It is difficult to predict whether a requirement for only the detection of visible moles will increase the detection rate sufficiently to reach the requirement of 98% detection based on one technique alone, e.g. HSI. Fluorescence was previously written off because it only focuses on the surface, but here can form a good supplement for the detection of visible quartz. By combining HSI and fluorescence, and possibly using 3D profiling, work will be done to develop a complete solution that can reach the 98% target without the number of false positives becoming too high.
Main objective:
To further develop hyperspectral imaging and fluorescence for the automatic detection of visible galls in fillets, spotted fish and saltfish/rockfish from frozen/thawed and fresh whitefish.
Sub-goals:
• To prepare an agreed requirements specification. What is to be defined as a visible gall that must be detected with developed technology?
• To optimize fluorescence imaging for the detection of clefts. That is to find the optimal excitation wavelength to separate the nematods from the fish meat.
• To develop algorithms for the detection of visible cysts based on HSI.
• Combining HSI and fluorescence for increased detection rate and lowest possible false positive rate.
• To create a commercial prototype for measurement, analysis and control of degrees."
