Color Constancy in Hyperspectral Imaging via Reduced Spectral Spaces
Researchers have explored how to improve illuminant estimation in hyperspectral imaging by reducing spectral dimensionality. They adapted the Color-by-Correlation (CbC) framework to analyze the impact of different spectral dimensionality reduction strategies on estimation performance. The study provides insights into efficiently using hyperspectral data for illuminant estimation, showing that compact spectral representations can outperform traditional RGB-based methods under certain conditions.
