A vision system to identify aflatoxin Contaminated cashews and pistachios

The aim of this research was to detect aflatoxin contaminated nuts (pistachios and cashews), applying a vision system sorting method. Two images per nuts (n = 82) were acquired in the optical range 410-600 nm. For each sample the main of the gray level of 3 Regions of Interest (ROI) was calculated. Finally, the optimal optical range to separate contaminated and uncontaminated nuts was selected through a statistical analysis.
