| # 3DLP Ablations |
|
|
| This companion dataset contains 450 real HDR image pairs from |
| the ambient-light and light-probe ablations of the anonymous 3D-anchored Light |
| Probes (3DLP) release. Each pair captures the same scene and camera view with |
| the target light probe switched on and off. The dataset accompanies the paper |
| *Do Image Editing Models Understand Lighting?* |
|
|
| ## What Is Included |
|
|
| ### Ambient-light ablation |
|
|
| `ambient_light_ablation` contains 300 complete image pairs. This |
| controlled experiment studies whether image-editing models can disentangle the |
| illumination caused by the target probe from the scene's existing ambient |
| lighting. The target remains the spherical probe used by the main 3DLP |
| benchmark, while the ambient sources are placed behind the camera so that the |
| requested on/off edit remains unambiguous. |
|
|
| The subset covers six ambient-light arrangements of increasing complexity: |
|
|
| - a point-like spherical source; |
| - a 60 cm x 120 cm area light; |
| - one directional lamp; |
| - two directional lamps; |
| - one complex basket lamp; and |
| - two complex basket lamps. |
|
|
| These conditions are recorded across multiple indoor scenes and viewpoints, |
| allowing the interaction between ambient illumination, scene geometry, |
| shadows, highlights, and the target probe's light transport to be compared. |
| This experiment is described in the supplemental section *Ambient Light |
| Complexity Evaluation*. |
|
|
| ### Light-probe-type ablation |
|
|
| `light_type_ablation` contains 150 complete image pairs captured with six |
| different target-probe geometries and emission patterns: |
|
|
| - spherical; |
| - shaded; |
| - light bar; |
| - directional; |
| - daylight; and |
| - basket. |
|
|
| This subset motivates the spherical probe used in the main benchmark. For a |
| turn-on edit, more complex lamp geometry also requires the model to infer a |
| more complex, spatially varying emission pattern. For a turn-off edit, that |
| pattern is already visible in the input image. The experiment is described in |
| the main paper section *Light Probe Ablation*. |
|
|
| Each metadata row describes one complete real light-on/light-off pair. All real |
| TIFF files present in the source ablation folders are included; generated model |
| outputs are intentionally excluded. One light-off TIFF in the ambient-light |
| subset has no corresponding light-on capture; it is included in the image tree |
| but is not listed as a complete metadata sample. |
|
|
| ## Dataset Layout |
|
|
| ```text |

| +-- ambient_light_ablation/ |
| | +-- metadata.jsonl |
| | +-- images/ |
| | +-- location_<i>/ |
| | +-- scene_<j>/ |

| ``` |
|
|
| Location, scene, view, and image identifiers are anonymized. Their numeric IDs |
| are stable across the two subsets and do not encode real place names. |
|
|
| ## Metadata |
|
|
| Both subsets use `metadata.jsonl`, with one JSON object per complete captured |
| pair: |
|
|
| - `image_on_file_name`, `image_off_file_name`: real HDR TIFF captures. |
| - `Ambient_Light`: the ambient-light arrangement or probe-light type. |
| - `u`, `v`: probe coordinates retained from the source metadata. |
| - `annotations`: optional shadow and highlight annotations. |
|
|
| ## Intended Use |
|
|
| These real TIFF captures support the ablation experiments reported with 3DLP. |
