| # Material Replacement Bench v1.0 |
|
|
| Frozen evaluation split for the interior-design material-replacement |
| benchmark: 1421 task specs (mask-aligned, watermark-free), of which |
| 1093 are `gt_clean` (the stored `output` edits only the mask and |
| matches the reference; the rest keep `output` as a non-exemplar reference |
| solution only). |
|
|
| Task: given `input` + `mask` + `reference` (or the mask-free `instruction`), |
| replace the masked object's material and change nothing else. Evaluation is |
| reference-free — outputs are scored on material correctness, outside-mask |
| preservation, geometry preservation, and lighting harmony, never on pixel |
| similarity to `output`. |
|
|
| Columns: `instruction` (rewritten, image-faithful), `material_category`, |
| `surface_type`, `mask_target_seen`, `mask_coverage`, `coverage_bucket`, |
| `gt_clean`, plus the four images. |
|
|
| Provenance: fully synthetic quadruples generated with OpenAI image models |
| via codex; curated from `Elfsong/vinhome_material_replacement` (algorithmic |
| QC + VLM semantic QC + instruction relabeling; see `curation/` there). |
