| # PAPE — COCO |
|
|
| Real COCO photographs edited by four image-editing models. Each manifest row is one language-specific pair: the source image, a semantically normal replacement, a semantically abnormal replacement of the same object, and a binary mask for each edit. Every pair in this folder has normal/abnormal mask IoU of at least 0.5. |
|
|
| 2,000 distinct COCO image ids are included. A source image can appear more than once when several objects, anomaly categories, or languages were edited. |

| ## Counts |
|
|
| | Editor | Directory | Pairs | Chinese | English | |
| | --- | --- | ---: | ---: | ---: | |
| | Qwen-Image-Edit-2511 | `qwen_image_edit_2511` | 3,754 | 1,864 | 1,890 | |
| | FireRed-Image-Edit-1.1 | `firered_image_edit_1.1` | 3,832 | 1,915 | 1,917 | |

|
|
| ## Split |
|
|
| `splits/split_seed2026.json` assigns COCO `image_id` values with seed 2026: 1,600 train, 200 validation, and 200 test. The same image id is used for every editor. ImageNet and Places are held out as test. |

| ## Files |
|
|
| ```text |
| <edit_model>/ |
| manifest.jsonl |
| source/ JPEG, suffix .jpg |
| normal/ PNG |
| abnormal/ PNG |
| masks/normal/ PNG |
| masks/abnormal/ PNG |
| ``` |
|
|
| Filenames follow `{sample_id}__{language}_{role}`, with roles `source`, `normal`, `abnormal`, `normal_mask`, and `abnormal_mask`. |
|
|
| `manifest.jsonl` fields used to load a row: |
|
|
| | Field | Meaning | |
| | --- | --- | |
| | `sample_id` | Source image, target object, and anomaly id | |
| | `image_id` | COCO file id, also the split key | |
| | `language` | `zh` or `en` | |
| | `edit_model_name` | Editor directory name | |
| | `anomaly_type` | One category below | |
| | `iou` | IoU between the normal and abnormal masks | |
| | `normal_prompt`, `abnormal_prompt` | Instructions applied to produce this row | |
| | `normal_prompt_zh`, `normal_prompt_en`, `abnormal_prompt_zh`, `abnormal_prompt_en` | Bilingual prompt fields stored with the row | |
|
|
| `source_paths` and `export_paths` are absolute paths from the original export machine. Load images from `source/`, `normal/`, `abnormal/`, and `masks/` in this folder. |

|
| ## Anomaly categories |
|
|
| | Id | Pairs | Share | Abnormal edit | |
| | --- | ---: | ---: | --- | |
| | `C1_physical_attribute` | 3,566 | 24.3% | Material or physical state is not one the object can have | |
| | `C2_spatial_relation` | 1,965 | 13.4% | Support, contact, containment, or scale is inconsistent | |
| | `C3_function_affordance` | 2,477 | 16.9% | The object does not support the use shown in the edit | |
| | `C4_scene_context` | 2,008 | 13.7% | A recognizable object does not belong in the scene | |
| | `C5_biological_structure` | 2,392 | 16.3% | Anatomy, part count, or bodily configuration is inconsistent | |
| | `C6_interaction_relation` | 2,260 | 15.4% | An action or relation between entities is incoherent | |
|
|
| The normal edit replaces the same object in a semantically ordinary way. Both edits are meant to keep location, scale, lighting, and viewpoint close to each other. |
|
|
| COCO photographs remain under the COCO dataset terms. This folder does not relicense them. |
