SwitchLight: Co-design of Physics-driven Architecture and Pre-training Framework for Human Portrait Relighting
<|reference_start|>SwitchLight: Co-design of Physics-driven Architecture and Pre-training Framework for Human Portrait Relighting: We introduce a co-designed approach for human portrait relighting that combines a physics-guided architecture with a pre-training framework. Drawing on the Cook-Torrance reflectance model, we have meticulously configured the architecture design to precisely simulate light-surface interactions. Furthermore, to overcome the limitation of scarce high-quality lightstage data, we have developed a self-supervised pre-training strategy. This novel combination of accurate physical modeling and expanded training dataset establishes a new benchmark in relighting realism.<|reference_end|>
