Hyperspectral Imaging Algorithms and Applications: A Review

This paper is not about microplastics. It is a broad review of hyperspectral imaging algorithms and their applications across agriculture, healthcare, earth sciences, industrial manufacturing, and security, tracing development from early image processing through modern deep learning approaches. While hyperspectral imaging can be applied to microplastic detection, this review covers the technology's full range of applications rather than focusing on environmental contamination.
