# BarDecode
BarDecode is a simple barcode reader project that can read barcodes from both images and webcam video streams. It uses Python's `opencv-python` for image processing and `pyzbar` for barcode decoding. The project demonstrates two modes: reading barcodes from an image file or live from a webcam.
## Features
- **Barcode Detection**: Detects and decodes barcodes from images and live camera feeds.
- **Image Processing**: Displays the decoded barcode with a rectangle drawn around it for easy identification.
- **Support for Various Barcode Types**: Can read various barcode types such as EAN13, QR code, UPC, etc.
## Installation
### 1. **Install Zbar Library**
`pyzbar` depends on the `zbar` library to decode barcodes. You need to install `zbar` on your macOS machine.
To install `zbar`, you can use Homebrew with the following command:
```bash
brew install zbar
```
This will install the zbar library, which is required by pyzbar to function correctly.
### 2. **Clone the repository**
```bash
git clone https://github.com/yourusername/BarDecode.git
cd BarDecode
```
### 3. **Set up a virtual environment (optional but recommended):**
```bash
python -m venv venv
source venv/bin/activate # On Windows use `venv\Scripts\activate`
```
### 4. **Install the dependencies:**
Install the necessary Python libraries with:
```bash
pip install -r requirements.txt
```
The required packages are:
- opencv-python - For image processing and displaying the barcode in images.
- pyzbar - For decoding barcodes from images.
## Usage
You can run the project in two modes:
### 1. **Reading from an Image**
To read barcodes from an image, call the read_barcode_from_image() function and provide the image path.
```bash
read_barcode_from_image('path_to_image_file.png')
```
It will display the image with a rectangle drawn around the barcode and output the decoded barcode data to the console.
### 2. **Reading from the Webcam**
To read barcodes in real-time using your webcam, call the read_barcode_from_camera() function.
```bash
read_barcode_from_camera()
```
Press ‘q’ to exit the webcam feed.
## Example
### Reading Barcode from an Image:
```bash
python main.py
```
The output will look like:
```plaintext
Decoded Barcode: 1234567890128 (Type: EAN13)
```
### Reading Barcode from Webcam:
Run the following command:
```bash
python main.py
```
The webcam will start, and you can scan barcodes in real time. Press ‘q’ to stop the webcam feed.
