+# Image to Line Art SVG Converter
+
+A Gradio-powered web application that converts images to line art and exports them as SVG files.
+
+## Features
+
+- Upload images via file upload or webcam
+- Convert images to clean line art using computer vision techniques
+- Adjustable parameters for line thickness, blur, and threshold
+- Export results as scalable SVG files
+- Real-time preview of the conversion
+
+## How it Works
+
+1. **Image Preprocessing**: Converts the input image to grayscale
+2. **Noise Reduction**: Applies median filtering to reduce noise
+3. **Edge Detection**: Uses adaptive thresholding to detect edges
+4. **Contour Extraction**: Finds and simplifies contours from the edges
+5. **SVG Generation**: Converts contours to SVG paths for scalable output
+
+## Usage
+
+1. Upload an image using the upload button or webcam
+2. Optionally adjust the parameters:
+   - **Line Thickness**: Controls the stroke width of the lines (1-5)
+   - **Blur Value**: Affects noise reduction (must be odd, 3-15)
+   - **Threshold Value**: Controls edge sensitivity (must be odd, 3-15)
+3. Click "Convert to Line Art" to process the image
+4. Download the generated SVG file
+
+## Technical Details
+
+- Built with Gradio for the web interface
+- Uses OpenCV for image processing and edge detection
+- Converts contours to SVG paths for vector output
+- Optimizes SVG size by simplifying contours
+
+## Requirements
+
+- Python 3.8+
+- See requirements.txt for dependencies
