Radio Frequency Detection and Classification of Microplastics in Water

Read the original on arXiv Machine Learning →

The study introduces a machine learning–assisted radio‑frequency dielectric spectroscopic cytometry platform for detecting and classifying micro‑plastic particles in water. Eight types of 10 µm nominal‑diameter micro‑plastics were distinguished in deionized water using RF scattering parameters measured at 0.2–9 GHz, achieving macro‑average F1‑scores, precision, and recall above 0.71. The method also maintained PET classification performance in saline media up to 6.6 % sea salt, demonstrating feasibility for rapid, single‑particle micro‑plastic identification in aqueous environments.

MWIR-4-Plastic: The Identification of Complex End-of-Life Industrial Plastic using Mid-wave Infrared Hyperspectral Imaging and Machine Learning

The paper presents the first publicly available hyperspectral imaging (HSI) dataset of shredded black plastics from end‑of‑life vehicle waste, covering four industrial polymers across RGB, VNIR, SWIR, and MWIR modalities. It introduces a multi‑modal spectral‑spatial framework that combines foreground isolation, pixel‑wise classification, and object‑level majority voting, leveraging hyperspectral transformers and chemometric band selection to accurately classify complex black plastics. The study benchmarks nine processing methods—including chemometric, machine learning, and deep learning architectures—providing a reproducible, comprehensive benchmark for industrial hyperspectral object analysis.
