| # RefStuff |
|
|
| This release contains two COCO 2014-derived splits for visual grounding with |
| reference-style horizontal rows of repeated non-person objects. |
|
|
| ## Layout |
|
|
| - `coco2014_candidates_4to8_unfiltered/`: 15,577 candidate images. Each has |
| one selected non-person COCO category with 4-8 annotated instances. |
| - `strict_ready_131/`: 131 visually screened samples with complete grounding |
| annotations. Every item passed whole-image row screening and individual |
| crop validation. |
|
|
| ## Strict grounding format |
|
|
| `strict_ready_131/grounding.jsonl` is the final annotation file. Each record |
| includes the source image, target category, COCO instance IDs, visual row |
| assignment, crop checks, and per-instance Chinese reference text. Reference |
| text follows this form: |
|
|
| `从上到下第N行从左数第K个<category>` |
|
|
| or: |
|
|
| `从上到下第N行从右数第K个<category>` |
|
|
| Rows are numbered from top to bottom. The left/right ordinal is selected for |
| each instance according to its side of the assigned horizontal row. |
|
|
| ## Provenance |
|
|
| Images and instance metadata originate from COCO 2014. The unfiltered split |
| is a candidate pool, not a final-quality row dataset. The strict split is the |
| screened subset intended for grounding use. |
