# Run the Preprocessing Script
We have written the preprocessing code of the CPR-Coach dataset. The preprocessing includs a series of merge, decompression and deletion operations.
The whole process may take 20-30 minutes.
Since the parallel processing is adopted, program interruption should be avoided.
After running the `process.sh` file, you can get the entire dataset.

```shell
sh ./process.sh
```

# Dataset Check
After the preprocessing, make sure that the structure of the dataset is same with the follow.
The total size of the dataset should be `451 GB`.

# Dataset Structure Description

In the initial version of the dataset, we only collected videos of a single person dressed in two different clothes. 
And only 59 types of double errors composite actions were explored. 
These data exist in `CPR_Dataset_S0`, `CPR_Dataset_S1`, `CPR_Double_Dataset_S0` and `CPR_Double_Dataset_S1`.

We put the initial version of this work into CVPR-2023, and the reviewers gave us valuable suggestions: further enrich the types of samples and composite errors.

Therefore, we subsequently improved this dataset and recruited several volunteers to conduct supplementary data collection. These data are stored in `SupC14_Dataset`, `SupDC59_Dataset` and `SupMC15_Dataset`. We divided these samples in the `ann` directory.
