S Zini, M Buzzelli, S Bianco… - IEEE Transactions on …, 2022‏ - ieeexplore.ieee.org
We present an efficient combination strategy for color constancy algorithms. We define a
compact neural network architecture to process and combine the illuminant estimations of …

[HTML][HTML] Angle-retaining chromaticity and color space: Invariants and properties

M Buzzelli - Journal of Imaging, 2022‏ - mdpi.com
The angle-retaining color space (ARC) and the corresponding chromaticity diagram encode
information following a cylindrical color model. Their main property is that angular distances …

On the evaluation of temporal and spatial stability of color constancy algorithms

M Buzzelli, I Erba - Journal of the Optical Society of America A, 2021‏ - opg.optica.org
