| Class-list object detection with WeVisOne-VL via vLLM. | |
| Give it an image dataset and a list of class names; it returns boxes for every | |
| instance of every class and pushes the dataset back to the Hub with a | |
| `detections` column in the same shape as qwen3vl-detect.py, so | |
| inspect-detections.py and the downstream labelling steps work unchanged. | |
| WeVisOne-VL (tencent/WeVisOne-VL-4B and -2B, Apache-2.0) is a Qwen3-VL model | |
| trained for grounding: open-vocabulary detection, referring, counting and | |
| pointing. It loads in stock vLLM. Use it when you know your classes; use | |
| qwen3vl-detect.py when you want a free-form instruction and descriptive | |
| sub-labels. | |
| Example (Hugging Face Jobs; the header above supplies image, flavor and secrets): | |
| hf jobs uv run \\ | |
| https://huggingface.co/datasets/uv-scripts/vlm-object-detection/raw/main/wevisone-detect.py \\ | |
| rishitdagli/cppe-5 your-username/cppe5-wevisone \\ | |
| --classes "Coverall,Face_Shield,Gloves,Goggles,Mask" \\ | |
| --split test --max-samples 20 --shuffle | |
| Measured behaviour (20-image smokes, IoU >= 0.5 against ground truth): | |
| * The model answers each class on its own, so one object can come back under | |
| several classes (a fox as Red Fox, Grey Fox and Coyote). Every box is kept; | |
| each box's `alt_labels` lists the other classes given to the same region | |
| (IoU >= --duplicate-iou), so a reviewer sees the ambiguity. | |
| * Keeping every box costs box precision on multi-class lists: each extra class | |
| name on the same object is an extra box (ENA24: 0.47 vs 0.90 merged). | |
| --merge-duplicates folds overlapping boxes of different classes into one box, | |
| labelled with the class listed first in --classes (there are no scores to | |
| choose by). Labels get worse when that order is arbitrary: ENA24 species | |
| recall fell from 0.75 to 0.30. Merge for coarse or priority-ordered classes, | |
| or dedupe downstream before using the boxes as training data. | |
| * Class names go into the prompt as plain phrases ("Face_Shield" is sent as | |
| "Face Shield"); the output label is the name exactly as you passed it. The | |
| prompt separates classes with ". ", so names cannot contain "." or ",". | |
| * There are no confidence scores. | |
| * Compared with qwen3vl-detect.py on Qwen3.6-35B-A3B: higher box recall on small | |
| objects and dense pages (cigarette ends 0.88 vs 0.79, newspaper pages 0.26 vs | |
| 0.15), similar box recall elsewhere, lower box precision by default (see | |
| above), and slightly weaker fine-grained labels (ENA24 species recall 0.75 vs 0.80). | |

| - `detections`: list of `{{bbox: [x1, y1, x2, y2], label, sub_label, alt_labels}}`. `bbox` is in | |
| original-image pixels. `sub_label` is always empty (WeVisOne gives class labels only); it is | |
| there so the schema matches `qwen3vl-detect.py`. `alt_labels` lists other classes the model | |
| gave the same region (IoU >= {args.duplicate_iou}); WeVisOne answers each class on its own, | |
| so one object can carry several class names. | |
| - `raw_response`: the model's raw answer, for re-parsing. | |
