"""AicDataset dataset for top-down pose estimation.
"AI Challenger : A Large-scale Dataset for Going Deeper
in Image Understanding", arXiv'2017.
More details can be found in the `paper
<https://arxiv.org/abs/1711.06475>`__
The dataset loads raw features and apply specified transforms
to return a dict containing the image tensors and other information.
AIC keypoint indexes::
0: "right_shoulder",
1: "right_elbow",
2: "right_wrist",
3: "left_shoulder",
4: "left_elbow",
5: "left_wrist",
6: "right_hip",
7: "right_knee",
8: "right_ankle",
9: "left_hip",
10: "left_knee",
11: "left_ankle",
12: "head_top",
13: "neck"
Args:
ann_file (str): Path to the annotation file.
img_prefix (str): Path to a directory where images are held.
Default: None.
data_cfg (dict): config
pipeline (list[dict | callable]): A sequence of data transforms.
dataset_info (DatasetInfo): A class containing all dataset info.
test_mode (bool): Store True when building test or
validation dataset. Default: False.
