STAR Relationship
STAR Relationship 是一个遥感场景图生成(Scene Graph Generation,SGG)数据集。仓库将原始大尺寸图片与结构化标注分开保存:
- 图片以普通文件形式位于
images/。 - train、validation 和 test 的结构化标注以 Parquet 保存。
- Dataset 中的
image字段是图片相对于仓库根目录的路径,不包含图片字节,也不会自动解码为 PIL 对象。
完整仓库约为 127 GB。使用 snapshot_download() 下载完整仓库前,请确认本地有足够的磁盘空间。
仓库结构
wliafe/star
├── README.md
├── images
│ ├── train
│ │ └── 0000.png
│ ├── validation
│ │ └── 0002.png
│ └── test
│ └── 0004.png
└── data
├── train-*.parquet
├── validation-*.parquet
└── test-*.parquet
本地源数据中的 val 在 Hugging Face Dataset 中命名为 validation。
数据字段
每行表示一张图片及其场景图标注:
id:图片文件名去除扩展名后的样本 ID。image:仓库相对路径,例如images/train/0000.png。width、height:原图宽高。polygons:对象 polygon 列表;每个点为[x, y],保留原始坐标和顶点顺序。labels:与polygons一一对应的对象类别。relations.subject_index:关系主语在对象数组中的索引。relations.object_index:关系宾语在对象数组中的索引。relations.predicate:关系类别。
test split 只有图片,polygons、labels 和三个关系数组均为空。
下载并读取
repo_type="dataset" 是 snapshot_download() 的参数;load_dataset() 直接使用仓库 ID,不需要传入 repo_type。
from pathlib import Path
from datasets import load_dataset
from huggingface_hub import snapshot_download
repo_dir = Path(
snapshot_download(
repo_id="wliafe/star",
repo_type="dataset",
)
)
dataset = load_dataset("wliafe/star")
sample = dataset["train"][0]
image_path = repo_dir / sample["image"]
print(sample["id"])
print(sample["image"])
print(image_path)
assert image_path.is_file()
snapshot_download() 返回仓库快照根目录,因此将它与 sample["image"] 拼接即可得到本地图片路径。不要直接把相对路径解释为当前工作目录下的文件。
使用 Pillow
from PIL import Image
with Image.open(image_path) as image:
image.load()
print(image.size)
使用 OpenCV
import cv2
image = cv2.imread(str(image_path), cv2.IMREAD_UNCHANGED)
if image is None:
raise RuntimeError(f"无法读取图片:{image_path}")
print(image.shape)
固定数据版本
如果训练或评测需要可复现的数据版本,请为下载和 Dataset 加载指定同一个完整 commit revision:
from pathlib import Path
from datasets import load_dataset
from huggingface_hub import snapshot_download
revision = "<full-commit-sha>"
repo_dir = Path(
snapshot_download(
repo_id="wliafe/star",
repo_type="dataset",
revision=revision,
)
)
dataset = load_dataset("wliafe/star", revision=revision)
image_path = repo_dir / dataset["train"][0]["image"]
这样 Parquet 标注与原始图片始终来自同一个仓库版本。
