# API

## Download 
1. Please visit the repository: https://github.com/Thomas-uestc/API
2. Download the tempate archive 'Template.zip' from the repository

### Description of Folders

- **datasets**: This folder should hold the raw datasets used for the project. 
- **export**: This folder is for files that include models.
- **result**: This folder is for pretrained model parameters
- **mats**: This directory stores MATLAB-related files, such as `.mat` files or other results generated during computation.
- **your script**: Your script should be placed at the same level as 'export'

## Usage Guide for `dulrs` Package

The `dulrs` package provides tools to calculate and visualize some evaluation matrix (heatmap, low-rankness, sparsity)of our models on various scenarios from different datasets.

### Installation

First, install the package using `pip`:

```bash
pip install dulrs
```

### Importing the Package

Import the package in your Python script:

```python
from dulrs import dulrs_class
```

### Available Functions

The package includes the following functions:

0. `dulrs_class(model_name, model_path, use_cuda=True, num_stages=6)`
1. `dulrs_class.heatmap(img_path, data_name,output_mat,output_png)`
2. `dulrs_class.lowrank_cal(img_path, model_name, data_name, save_dir)`
3. `dulrs_class.lowrank_draw(model_name, data_name, mat_dir, save_dir)`
4. `dulrs_class.sparsity_cal(img_path, model_name, data_name, save_dir)`

### Function Descriptions and Examples

#### 0. `dulrs_class(model_name, model_path, use_cuda=True, num_stages=6)`
The `dulrs_class` in the `dulrs` package is used to initialize the models with pretrained parameters and including following functions.

#### 1. `dulrs_class.heatmap(img_path, data_name, output_mat, output_png)`

The `dulrs_class.heatmap` function in the `dulrs` package allows users to draw and save the heatmaps obtained from different stages.

#### 2. `dulrs_class.lowrank_cal(img_path, model_name, data_name, save_dir)`

The `dulrs_class.lowrank_cal` function in the `dulrs` package allows users to calculate and save the low-rankness data with mat format.

#### 3. `dulrs_class.lowrank_draw(model_name, data_name, mat_dir, save_dir)`

The `dulrs_class.lowrank_draw` function in the `dulrs` package allows users to draw the low-rankness figure based on the calculated low-rankess data and save with png format.

#### 4. `dulrs_class.sparsity_cal(img_path, model_name, data_name, save_dir)`

The `dulrs_class.sparsity_cal` function in the `dulrs` package allows users to calculate and save the sparsity data with mat format.

> ```

### 📜 Script Example

   ```python
    from dulrs import dulrs_class
    import torch

    # Set CUDA as default device
    torch.set_default_tensor_type('torch.cuda.FloatTensor' if torch.cuda.is_available()     else 'torch.FloatTensor')
    dulrs = dulrs_class(
    model_name="rpcanet_pp",
    model_path="./result/ISTD/1K/s6_best.pkl",     # Path for pretrained parameters
    num_stages=6,
    use_cuda=True)

    # For heatmap generation
    heatmap = dulrs.heatmap(
        img_path="./datasets/IRSTD-1k/test/images/000009.png",
        data_name="IRSTD-1k_test_images_000009",
        output_mat="./heatmap/mat",  # If users want to save the data as .mat format.    Default=None
        output_png="./heatmap/png"   # If users want to save the figure as .png format.  Default=None
    )

    # For lowrank calculation
