+# Lane-Line-Detection
+
+## Description
+
+Lane-Line-Detection is a project aimed at detecting lane lines in video streams or images using computer vision techniques. This project leverages OpenCV and Python to identify and highlight lane markings, which is a crucial component for autonomous driving systems.

+   python lane_detection.py --video_path path/to/your/video.mp4
+   ```
+
+2. To detect lane lines in an image:
+   ```bash
+   python lane_detection.py --image_path path/to/your/image.jpg
+   ```
