| # Déjà View |
|
|
| DVLT reconstructs camera poses and 3D geometry from images or video. |
| The hosted app serves DVLT only, with 8–16 inference steps and cached |
| 16-step examples. Visualization controls are under Advanced. |
| Model selection is available only from the command line, not in the GUI. |
| The **Filter sky** control is enabled by default and available under Advanced. |
|
|
| Reconstruction displays and logs **Network forward pass** time with CUDA |
| synchronized before and after the network call. Loading, preprocessing, |
| prediction postprocessing, sky filtering and file export are excluded. |
| Displayed throughput FPS is input frame count divided by network forward seconds. |
| Visualization-only changes retain the last timing; cached examples do not |
| run the network or display a newly measured time. |
|
|
| The intended deployment uses **Protected** visibility: the app is publicly |
| accessible at its Hugging Face app URL, while this source repository stays |
| private. Visibility is a Space setting, not controlled by this README. |
|
|
| ## Uploads and temporary results |
|
|
| Live inference accepts JPEG, PNG or WebP images and supported video files, |
| up to 300 images or sampled video frames, at most |
| 16 megapixels per frame. Uploads are limited to 100 MB per file at the |
| HTTP upload boundary and 256 MiB total per submitted collection. Videos |
| are sampled at 0.5–30 FPS, with no limit on the original video frame count. |
| Video decoding has a 30-second timeout. |
|
|
| Uploads, previews and reconstruction downloads use temporary server storage. |
| Gradio cache cleanup is configured to remove files older than one hour, |
| checked every five minutes while the server is running. In-memory session |
| state has a one-hour expiry. These application settings do not establish |
| Hugging Face platform-log, backup or infrastructure retention. Those must |
| be confirmed separately before any broader retention promise. |
|
|
| Results include downloadable GLB and RRD files. Fixed examples also expose |
| input previews, depth previews and the camera/depth files listed in their |
| manifest. Cached examples are persistent demonstration assets, separate |
| from visitor uploads. Do not upload confidential or sensitive content. |
|
|
| ## Licensing and model identity |
|
|
| The code is primarily Apache 2.0 with third-party exceptions documented in |
| `THIRD_PARTY_LICENSES.md` and `LICENSES/`. The model weights have separate |
| NVIDIA non-commercial research/evaluation terms; the code license does not |
| license the model or establish the approved terms of this hosted service. |
| The hosted model is pinned to `nvidia/dvlt` revision |
| `20f919875a00ee3ab2e840f2f31580f4652b7c5e`. |
|
|
| Service terms and privacy notices must reflect the approved release review. |
