 # Hyperspectral foreign-object detection in walnuts
 
-Walnut kernels and shell fragments with foreign objects, recorded with a Cubert Ultris XMR hyperspectral camera between August and October 2026 for Cubert's foreign-object demonstration: first on a lab station with a blue mat, then on the demonstration stand with production lights, a turntable and a belt. The contaminants are stones, stems, rubber, aluminium shards and plastic imitation shells, placed by hand into the product; the shell fragments are labelled as a class of their own, so the same frames serve shell segmentation and unsupervised foreign-object detection. The trained pipelines fitted on these recordings are published in the companion model repository of the same name.
