## Introduction

This repository demonstrates essential **computer vision** tasks often required in real-world scenarios such as robotics, surveillance, and industrial quality control. By leveraging OpenCV functions, the project performs:

- **Color Detection:** Isolating objects based on hue, saturation, and value (HSV color space).  
- **Shape Detection:** Identifying and labeling standard geometrical shapes (triangle, rectangle, pentagon, circle) using contour approximation.  
- **Edge Detection:** Extracting prominent edges and boundaries via the Canny edge detection algorithm.  
- **Image Filtering:** Demonstrating both Gaussian blur (to reduce noise) and custom kernel sharpening (to enhance edges).

This comprehensive project serves as an excellent portfolio piece to exhibit your understanding of classic computer vision algorithms and Python scripting. Recruiters can see your skills in data processing, algorithmic thinking, and effective code documentation.

---

## Features

- **Flexible Color Detection**: Easily modify HSV boundaries to detect different colors in various lighting conditions.  
- **Accurate Shape Classification**: Use polygon approximation to label shapes with minimal false positives.  
- **Robust Edge Detection**: Generate crisp, well-defined edges using the Canny algorithm.  
- **Multi-Stage Image Filters**: Apply Gaussian blur to reduce noise and a custom convolution kernel to sharpen and highlight details.

├── main.py                 # Main script that processes the image
├── Results/                # Directory containing the original & processed images

```

**Note:** Adjust the directory names based on your own layout.

---

## Requirements

- **Python 3.6+**  
- **OpenCV (cv2)**  
- **NumPy**  
- **matplotlib**

You can include a `requirements.txt` file with these dependencies, for example:

```txt
opencv-python
numpy
matplotlib
```

---

## Installation

1. **Clone the repository**:
   ```bash
   git clone https://github.com/username/Detection-through-OpenCV-functions.git
   cd Detection-through-OpenCV-functions
   ```
2. **Create and activate a virtual environment** (optional, but recommended):
   ```bash
   python -m venv venv
   source venv/bin/activate       # For Linux/Mac
   venv\Scripts\activate          # For Windows
   ```
3. **Install dependencies**:
   ```bash
   pip install -r requirements.txt
   ```
   Or individually:
   ```bash
   pip install opencv-python numpy matplotlib
   ```

---

## Usage

1. **Place your target images** in the `Results/` folder or specify your own directory.
2. **Run the script** by providing the path to the image:
   ```bash
   python main.py
   ```
3. **Observe** the series of matplotlib windows showcasing:
   - The original image
   - The color-filtered image
   - The shape-labeled image
   - The edge-detected image
   - The blurred image
   - The sharpened image

**Example** usage inside `main.py`:

```python
# Use any image path for testing
image_path = 'Results/original.jpg'
process_image(image_path)
```

## Roadmap

- [ ] **Video Stream Processing**: Extend the script to process live camera feeds or video files in real-time.  
- [ ] **Additional Shape Detection**: Implement more robust shape classification for polygons with more complex criteria.  
- [ ] **Object Tracking**: Add functionality to track detected objects across frames.  
- [ ] **Deep Learning Integration**: Incorporate models like YOLO or Faster-RCNN for more sophisticated object detection tasks.
