Towards Integrating Multi-Spectral Imaging with Gaussian Splatting
Contributions:
• Formulation and comparison of multi-spectral integration strategies: We introduce and systematically evaluate three optimization paradigms—SEPARATE, SPLIT, and JOINT—for incorporating additional spectral bands into 3DGS.
• We propose a set of optimizations for the JOINT strategy for multi-spectral reconstruction, along with practical insights from this analysis.
• We examine how spectral cross-talk between spectral bands can improve reconstruction quality.
