leafy vegetables - Insect
Detection of aphids and thrips on lettuce.
Industry
fresh produce
Solution
Beyond Safety
Foreign Bodies (insect, objects) Detection
Goal
Develop a tool for detection of a very small insects on lettuce.
Methodologies Used
Hyperspectral imaging, Physical properties, Chemometric tools
Process
Beyond addresses the need for improved shelf life and contamination detection. Hyperspectral imaging allows the physiological and biochemical states assessment of leafy greens to optimize storage conditions as well as insects, debris and biofilm detection to improve the food safety.
Insect detection on and under Boston lettuce leaves. Real RGB representation (left), RGB reconstruction from HSI data (middle) and after PCA analysis of HSI data images (right). Insects identified by white circles are on the leaf, while the one identified by a red circle is located under the leaf.
Insect detection on lettuce leaves. Mathematical transformation of HSI data to visualise insects of sizes of a few tens of microns.
