Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Use IBRNet instead of LLFF without per-scene tuning | Novel-view synthesis · Diffuse Synthetic 360°; Realistic Synthetic 360°; Real Forward-Facing | PSNR, SSIM, and LPIPS: PSNR: 34.38 -> 37.17; 24.88 -> 25.49; 24.13 -> 25.13 | Helped |
| Fine-tune the pretrained model per scene instead of using NeRF | IBRNet · Diffuse Synthetic 360°; Realistic Synthetic 360°; Real Forward-Facing | PSNR, SSIM, and LPIPS: PSNR: 40.15 -> 42.93; 31.01 -> 28.14; 26.50 -> 26.73 | Mixed |
| Add the ray transformer for cross-sample density reasoning (ablation) | IBRNet · Real Forward-Facing | PSNR: 21.31 -> 25.13 | Helped |
| Add view-direction inputs and weighted pooling (ablation) | IBRNet · Real Forward-Facing | PSNR: 24.20 -> 25.13 | Helped |
| Blend source image colors rather than regress RGB directly (ablation) | IBRNet · Real Forward-Facing | PSNR: 24.73 -> 25.13 | Helped |
