An Assessment of Hyperspectral Imaging and Target detection

Abstract: Hyperspectral Imaging is a recent trend in the field of remote sensing. Over the past few years hyperspectral imaging has been emerged as rapidly developing technology to process and analyze the images. This technique has gained interest in wide area of applications such as food processing, mineralogy, environment, vegetation, astronomy, surveillance, eye care, chemical imaging, military and so on.. This article presents the overview of hyperspectral imaging, outlines the energy distribution from source to sensor, discussing about the radiation interaction with the earth, summarizing the differences between multispectral and hyperspectral data and finally briefing the hyperspectral imaging algorithms in target detection.

Keywords: Hyperspectral Imaging, multispectral, electromagnetic radiation, target detection.
