Skin Tone in Hyperspectral Imaging and Its Implications for Fairness in AI. [PDF]
J BiophotonicsThis study investigates whether skin tone is systematically encoded in hyperspectral imaging (HSI) data and how this influences AI‐based classification. The results show differences in classification performance across skin tones when using both unsupervised and supervised learning methods, indicating the presence of potential bias. ABSTRACT Artificial

High-throughput, multiplexed pushbroom hyperspectral microscopy
Optics Express, 2008 We describe a high-throughput hyperspectral microscope. The system replaces the slit of conventional pushbroom spectral imagers with a static coded aperture mask. We present the theoretical underpinnings of the aperture coded spectral engine and describe two proof-of-concept experimental implementations. Compared to a conventional pushbroom system, the
