Hyperspectral imaging and its applications: An Overview

Recording of the spectral information together with spatial information is useful for many applications.Hyperspectral Imaging (HSI) is a recently developed imaging modality which is capable of recording both the spatial (x, y) and spectral (λ) information of a scene.Thereafter, several applications have been shown using HSI.In this review, we discussed some of the recent implementations of HSI that aimed at addressing several scientific research problems.We also brief about some of the existing types of HSI cameras.In some of the recent works, Deep Learning (DL) frameworks have been extensively used for several HSI related problems.We have provided insights on some of the recent implementations of DL on HSI based problems.
