The Hyperspectral imaging used for the first time by NASA for remote sensing application originates by combing two most powerful subjects; Imaging Science and Spectroscopy. Whereas the human eye visualize objects over a narrow band of the electromagnetic spectrum (400 – 700nm); Hyperspectral imaging device could record images with high spatial and spectral resolution over a broad range of the electromagnetic spectrum. This fusion of spatial and spectral information opens a new avenue for analysis, and a unique opportunity for processing and understanding characteristics of an image scene. The goal of hyperspectral imaging is to obtain the spectrum for each pixel in the image of a scene, with the purpose of finding objects, identifying materials, or detecting processes.
Today, hyperspectral imaging systems are available for applications in astronomy, agriculture, biomedical imaging, geosciences, physics, and surveillance. In this presentation I will describe few application areas (mainly application of Hyperspectral Imaging in digital pathology) we are working in past few years and pathways to make cost-effective hyperspectral imaging solution to different fields. |
