-## Dataset Overview
-
-This dataset contains a collection of images generated by **Stable Diffusion v2 Inpaint** through outpainting, along with bounding box annotations indicating the 鈥渙riginal image region鈥?within each outpainted image. The dataset is mainly intended for research tasks such as image cropping, original frame recovery, composition-aware cropping, and outpainting-aware visual understanding.
-
-Each sample contains:
-
-- An outpainted image;
-- `orig_bbox`: the location of the original image in the expanded canvas;
-- `composition_tags`: a list of image composition tags, some of which may be empty.
-
-## Data Generation Pipeline
-
-![pipeline_en](./assets/pipeline_en.png)
-
-The data generation pipeline is as follows:
-
-1. Collect professional photographs or high-aesthetic-score images.
-2. Obtain or generate image descriptions, for example by using BLIP to generate captions.
-3. Set the expansion margins.
-4. Use **Stable Diffusion v2 Inpaint** to complete the expanded regions.
-5. Use positive prompts to constrain the generated content.
-6. Use negative prompts to reduce undesired content, such as `frame`, `border`, `text`, `watermark`, etc.
-7. Perform artifact detection and consistency detection on the generated results.
-8. Conduct manual inspection.
-9. Keep the samples that pass quality control, and record the bbox of the original image region to form training pairs. 
-
-
-`orig_bbox` uses the following format:
-
-```text
-[x_min, y_min, x_max, y_max]
-```
-
-This bbox represents the position of the original image region in the outpainted canvas, rather than an object bounding box in object detection.
-

-```
-
-Each line in `metadata.jsonl` corresponds to one sample, for example:
-
-```json

-  "orig_bbox": [281, 77, 881, 487],
-  "composition_tags": ["HORI2"]
-}
-```
-
-### Field Description
-
-- `file_name`: the relative path of the outpainted image.
-- `orig_bbox`: the bounding box of the original image region in the outpainted canvas, in the format `[x_min, y_min, x_max, y_max]`.
-- `composition_tags`: a list of composition tags parsed from the original dataset. If there is no reliable composition tag, it is an empty list `[]`.
-
-## Dataset Statistics

-| HORI2 | 1,956 |
-| HORI3 | 1,694 |
