# Edge-Aware Image Denoiser

A Gradio app for testing edge-preserving image denoising methods.

## Methods

- Perona-Malik diffusion
- Total Variation denoising
- Bilateral filtering

## Features

- Upload an image
- Optionally add Gaussian noise for testing
- Compare original, noisy, and denoised images
- Adjust denoising settings
- View quality metrics when synthetic noise is added
- Download noisy and denoised images

## Run locally

```bash
pip install -r requirements.txt
python app.py
```

## Project files

```text
app.py
edge_aware_denoiser.py
requirements.txt
test_denoiser.py
```

## Usage

For already noisy images, leave synthetic noise turned off. Use Perona-Malik or Total Variation when edge preservation matters. Use Bilateral filtering for lighter smoothing.
