What is HSI?

HSI typically refers to Hyperspectral Imaging. It's a technique that captures and processes images across a wide range of the electromagnetic spectrum. Unlike traditional imaging which captures red, green, and blue light, HSI captures hundreds of narrow spectral bands. This creates a detailed spectral signature for each pixel in the image, enabling the identification and analysis of materials based on their unique spectral reflectance properties. HSI is commonly used in agriculture (e.g., crop monitoring, disease detection), environmental monitoring (e.g., water quality assessment, pollution detection), defense and security (e.g., target detection, surveillance), and medical diagnostics (e.g., tumor detection, tissue analysis).
