Evaluation of 3D Scene Expansion performance using fidelity and quality metrics (PSNR, SSIM, LPIPS, GPT/H metrics) on the ETH and online collections dataset.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | 3D Scene Expansion |
| Dataset (including any stated split) | ETH and online collections |
| Metric | PSNR |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 5 of 5 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [PSNR](<https://www.sota2.com/research/sota/3d-scene-expansion-on-eth-and-online-collections.md?metric=PSNR>): Higher is better; unit: SCALAR.

- [SSIM](<https://www.sota2.com/research/sota/3d-scene-expansion-on-eth-and-online-collections.md?metric=SSIM>): Higher is better; unit: PERCENT.

- [LPIPS](<https://www.sota2.com/research/sota/3d-scene-expansion-on-eth-and-online-collections.md?metric=LPIPS>): Lower is better; unit: SCALAR.

- [GPT-IS](<https://www.sota2.com/research/sota/3d-scene-expansion-on-eth-and-online-collections.md?metric=GPT-IS>): Higher is better; unit: SCALAR.

- [GPT-RQ](<https://www.sota2.com/research/sota/3d-scene-expansion-on-eth-and-online-collections.md?metric=GPT-RQ>): Higher is better; unit: SCALAR.

- [H-IS](<https://www.sota2.com/research/sota/3d-scene-expansion-on-eth-and-online-collections.md?metric=H-IS>): Higher is better; unit: SCALAR.

- [H-RQ](<https://www.sota2.com/research/sota/3d-scene-expansion-on-eth-and-online-collections.md?metric=H-RQ>): Higher is better; unit: SCALAR.
