aiverify-blur-corruptions 2.2.0
Part of AI Verify image corruption toolbox. This package includes algorithms that adds blur corruptions (defocus, gaussian, glass, horizontal motion, vertical motion and zoom Blur) to images at different severity levels, to test the robustness of machine learning models.
Requires Python: <3.13,>=3.10

# Algorithm - Blur Corruptions

## Description

- Robustness plugin with blur corruptions

## License

- Licensed under Apache Software License 2.0

## Developers

- AI Verify

## Installation

Each test algorithm can now be installed via pip and run individually.

```sh
pip install aiverify-blur-corruptions
```

## Example Usage

Run the following bash script to execute the plugin

```sh
#!/bin/bash

root_path="<PATH_TO_FOLDER>/aiverify/stock-plugins/user_defined_files"

python -m aiverify_blur_corruptions \
  --data_path $root_path/data/raw_fashion_image_10 \
  --model_path $root_path/pipeline/sample_fashion_mnist_sklearn \
  --model_type CLASSIFICATION \
  --ground_truth_path $root_path/data/pickle_pandas_fashion_mnist_annotated_labels_10.sav \
  --ground_truth label \
  --file_name_label file_name \
  --set_seed 10
```

If the algorithm runs successfully, the results of the test will be saved in an `output` folder.

## Including Specific Corruptions

### Usage

By default, **all** corruption functions are applied. You can use the `--corruptions` flag to specify which functions to run.

```sh
--corruptions [FUNCTION_NAME ...]
```

### Options

- `all` -> Runs all blur corruption functions (default)
- `gaussian_blur`
- `glass_blur`
- `defocus_blur`
- `horizontal_motion_blur`
- `vertical_motion_blur`
- `zoom_blur`

### Example: Applying only Gaussian Blur and Defocus Blur corruptions

```sh
#!/bin/bash

root_path="<PATH_TO_FOLDER>/aiverify/stock-plugins/user_defined_files"

python -m aiverify_blur_corruptions \
  --data_path $root_path/data/raw_fashion_image_10 \
  --model_path $root_path/pipeline/sample_fashion_mnist_sklearn \
  --model_type CLASSIFICATION \
  --ground_truth_path $root_path/data/pickle_pandas_fashion_mnist_annotated_labels_10.sav \
  --ground_truth label \
  --file_name_label file_name \
  --set_seed 10
  --corruptions gaussian_blur defocus_blur
```

## Customizing Parameters

To fine-tune the corruption parameters, use the [Blur Corruption Playground Notebook](./playground.ipynb). This notebook allows you to:

✅ Visualize the effects of different corruption functions.

✅ Experiment with different parameter values.

✅ Apply custom values in the CLI using flags like:

```sh
#!/bin/bash

root_path="<PATH_TO_FOLDER>/aiverify/stock-plugins/user_defined_files"

python -m aiverify_blur_corruptions \
  --data_path $root_path/data/raw_fashion_image_10 \
  --model_path $root_path/pipeline/sample_fashion_mnist_sklearn \
  --model_type CLASSIFICATION \
  --ground_truth_path $root_path/data/pickle_pandas_fashion_mnist_annotated_labels_10.sav \
  --ground_truth label \
  --file_name_label file_name \
  --set_seed 10
  --gaussian_blur_sigma 1.0 2.0 3.0
```

## PyTorch/TensorFlow support

To use a custom PyTorch/TensorFlow model with this plugin, follow the steps below:

1. **Install PyTorch/Tensorflow**

   Ensure you have installed a PyTorch/TensorFlow version compatible with your model.

2. **Specify Model Path**

   Use the `--model_path` command-line argument to specify the path to a **folder** containing:

   - The model class definition (e.g., `model.py`).
   - The model weights file (e.g., `model_weights.pt`).

3. **Implement a `predict` Function**

   Your model class must implement a `predict` function. This function should:

   - Accept a batch of image file paths as input.
   - Return a batch of predictions.

   For reference, see the sample implementation in `user_defined_files/pipeline/sample_fashion_mnist_pytorch`.

### Example Directory Structure

```bash
<model_path>/
├── model.py             # Contains the model class definition
├── model_weights.pt     # Contains the trained model weights
```

### Example `predict` Function (PyTorch)

```python
# model.py
from typing import Iterable

import numpy as np
import torch
from PIL import Image
from torchvision import transforms


class CustomModel(torch.nn.Module):
    def __init__(self):
        super().__init__()
        # Define your model architecture here
        ...

    def forward(self, x):
        # Define the forward pass
        ...

    def predict(self, image_paths: Iterable[str]) -> np.ndarray:
        transform = transforms.Compose([
            transforms.Resize((224, 224)),
            ...,
            transforms.ToTensor(),
        ])
        images = [Image.open(path).convert("RGB") for path in image_paths]
        image_tensors = torch.stack([transform(image) for image in images])

        self.eval()
        with torch.no_grad():
            predictions = self(image_tensors).argmax(dim=1).detach().cpu().numpy()
        return predictions
```

By following these steps, you can integrate your custom PyTorch/TensorFlow model into the corruption plugin.

#!/bin/bash
docker run \
  -v $(pwd)/stock-plugins/user_defined_files:/input \
  -v $(pwd)/stock-plugins/aiverify.stock.image-corruption-toolbox/algorithms/blur_corruptions/output:/app/aiverify/output \
