Survey on Hyperspectral Imaging Application

Hyperspectral imaging (HSI) is a powerful technique that captures images across multiple narrow and contiguous wavelength bands, providing detailed spectral information for each pixel in an image. This rich spectral and spatial data enables precise analysis, opening new opportunities in a wide range of applications across various fields, from biology and environmental science to agriculture and beyond. The capability of HSI to capture unique spectral signatures allows for advanced material classification, chemical detection, and biological analysis, providing insights that are not achievable through traditional imaging methods. This paper presents a comprehensive survey of HSI applications, highlighting how this technology has transformed research and industry practices by enabling nuanced data interpretation, accurate diagnostics, and enhanced monitoring capabilities across diverse sectors.
