Hyperspectral imaging LED and incandescent light source comparison for food quality inspection

Popis výsledku v původním jazyce

Incandescent light sources are typical lighting types for Vis-NIR hyperspectral imaging. New broadband LED-based lights start to appear as a possible substitute for incandescent light sources due to the development of new LED dye types. Two light sources (Tungsten-halogen lamp and hyperspectral LED Effilux EFFI-Flex-HSI-100-SD-P2) for the Vis-NIR (400-1000 nm) hyperspectral imaging were compared on 15 samples of Gothajsky cooked salami slices. The goal was to compare these two light source technologies (old incandescent and new LED-based) in the matter of image quality. Images were scored using no-reference quality metrics (BRISQUE, NIQE, PIQE). There was a strong correlation between the mean values of the scoring metrics (BRISQUE R=0.9245, NIQE R=0.8933, PIQE R=0.9779). Results show the main advantage of the LED light is no heat stress of the samples resulting in more stable results with less glare. The main disadvantage of LED light was a lower illumination power resulting in higher exposition time needed.
