Spectrum Aware Illumination Estimation Using Multispectral Image
Researchers have developed a novel deep learning framework for illuminant spectrum estimation (ISE) using multispectral images. This framework incorporates a spatio-spectral feature extraction block with spectral attention mechanisms to better leverage spectral information and preserve relevant spatial features. The proposed method also includes an illuminant prior and a spectral-domain transform, enabling effective transfer of learned spectra across different sensor spaces without retraining. A new real-world dataset and extensive experiments demonstrate the method's superior accuracy compared to existing models. AI
