Hyperspectral imaging – a short review of methods and applications

Abstract

This paper takes a look at the state-of-the-art solutions in the field of spectral imaging systems by way of application examples. It is based on a comparison of currently used systems and the challenges they face, especially in the field of high-altitude imaging and satellite imaging, are discussed. Based on our own experience, an example of hyperspectral data processing is presented. The article also discusses how modern algorithms can help in understanding the data that such images can provide.
