The quantitative results of OOD relighting on "CatSmall" are shown as follows. The training time and inference time are calculated based on their specific hardware.
| PSNR | SSIM | LPIPS | Training time | Inference time | Hardware | |
|---|---|---|---|---|---|---|
| NRHints | 24.14 | 0.9101 | 0.1265 | 16 hours | 150 seconds per frame | four NVIDIA RTX 4090 GPUs |
| Ours | 25.17 | 0.9297 | 0.1135 | 40 minutes | 0.05 second per frame | a single NVIDIA RTX 3090 GPU |
Visualizations of several testing illuminations are shown below. As shown in the figure, NRHints fails to infer the inherent lighting logic, such as ignoring shadows (light#1) or highlights (light#3), and tends to produce over-smoothing surfaces (light#2).
We will provide the results and visualizations of other scenes as soon as they are available.
