Hyperspectral imaging is an emerging non-invasive imaging technology that can be used in several applications such as medical diagnostics, pharmaceutical applications, image-guided surgery, defence, security, food quality analysis, mining, geology, industrial applications, and environmental analysis among others. The hyperspectral imaging (HSI) technology examines a broad spectral range of light frequencies ranging from ultra-violet (UV) to infrared (IR), by developing a hypercube data which is a three-dimensional dataset having one spectral dimension and two spatial dimensions.
