## Core Ideas
![idea](https://raw.githubusercontent.com/xuanyuzhang21/PCA-CASSI/main/asserts/PCA-CASSI.png)

## Environment

```shell
pip install -r requirements.txt
```
## Train

Please download the CAVE dataset from [TSA-Net](https://github.com/mengziyi64/TSA-Net) and put it into the `./datasets` directory.

Two-shot Training
```
python train.py --template pca --outf ./exp/pca/ --method pca
```

Single-shot Training
```
python train_singleshot.py --template pca --method rnd --outf ./exp/rnd/
```

## Test

Two-shot sampling and reconstruction. The model checkpoint file is provided in `./checkpoints/model.pth`.
```
python test.py --template pca --outf ./exp/pca/ --method pca --pretrained_model_path ./checkpoints/model.pth
```

Single-shot reconstruction. The model checkpoint file is provided in `./checkpoints/model_singleshot.pth`.
```
python test_singleshot.py --template pca --outf ./exp/rndhrnet/ --method rnd --pretrained_model ./checkpoints/model_singleshot.pth
```
