Hyperspectral Imaging for Food Quality
Analysis and Control

Based on the integration of image processing and spectroscopy techniques,
hyperspectral imaging is a novel technology for obtaining both spatial and
spectral information from an object. In recent years, hyperspectral imaging
has rapidly emerged as and matured into one of the most powerful and
fastest-growing non-destructive tools for food quality analysis and control.
Using the hyperspectral imaging technique, the spectrum associated with
each pixel in a food image can be used as a fingerprint to characterize the
biochemical composition of the pixel, thus enabling the visualization of the
constituents of the food sample at pixel level. As a result, hyperspectral
imagery provides the potential for more accurate and detailed information
extraction than is possible with any other type of technology for the food
industry.
