LED Matrix Design for Multispectral Imaging

Despite many benefits and applications of spectral imaging, and different techniques being proposed, not much attention has been given to the evaluation of the quality of spectral images and imaging systems. There are some studies being done in the area of spectral image quality, however in specific application domains only. This paper provides a comprehensive and critical literature review on existing research in the area of spectral image quality. The quality of a spectral image, unlike a color image, depends on different factors like characteristics of scene, sensor used and algorithms applied. Most of the spectral quality works so far done are based on the final spectral image only. However, one or more attributes in different stages in the spectral imaging workflow may influence, directly or indirectly, the quality of the spectral image. We try to identify important attributes, which we believe would be useful in describing the quality of a spectral image.
