https://github.com/opencv/opencv/tree/master/data/haarcascades In this video on OpenCV Python Tutorial For Beginners, we are going to see How we can do Face Detection using Haar Feature based Cascade Classifiers. By the end of the tutorial, you will be able to build a lane-detection algorithm fueled entirely by Computer Vision.
OpenCV is an image processing library created by Intel and later supported by Willow Garage and now maintained by Itseez. opencv is available on Mac, Windows, Linux. Works in C, C++, and Python.
it is Open Source and free. opencv is easy to use and install. Starting with an overview of what the course will be covering, we move on to discussing morphological operations and practically learn how they work on images. We will then learn contrast enhancement using equalization and contrast limiting. Finally we will learn 3 methods to subtract the background from the video and implement them using OpenCV. At the end of this course, you will have a firm grasp of Computer Vision techniques using OpenCV libraries. This course will be your gateway to the world of data science. Feel the real power of Python and programming! The course offers you a unique approach of learning how to code by solving real world problems. resources:

In this tutorial, you will learn how to build a face detection application with Python using OpenCV, a powerful computer vision library. Face detection is a fundamental task in computer vision, and OpenCV provides robust tools to accomplish this task efficiently. Here are the key topics covered in this tutorial: 1. Introduction to Face Detection: Understand the importance of face detection and its applications in various fields. 2. Installing OpenCV: Learn how to install the OpenCV library for Python. 3. Loading an Image or Video: Read an image or video stream using OpenCV to prepare it for face detection. 4. Haar Cascade Classifier: Explore Haar Cascade classifiers, which are pre-trained models for face detection provided by OpenCV. 5. Implementing Face Detection: Write Python code to apply the Haar Cascade classifier and detect faces in the loaded image or video stream. 6. Displaying Detected Faces: Visualize the detected faces by drawing rectangles around them on the original image or video frames. 7. Handling Multiple Faces: Handle scenarios with multiple faces in an image or video and detect all of them. 8. Real-Time Face Detection: Extend the face detection to work in real-time with your computer's webcam or any video input source. 9. Fine-Tuning Parameters: Learn how to fine-tune parameters of the Haar Cascade classifier for better face detection performance. 10. Performance and Limitations: Understand the limitations of the face detection approach and explore potential ways to improve it. By the end of this tutorial, you will have a working Python program that can detect faces in images or videos using OpenCV's Haar Cascade classifiers. Face detection is a fundamental skill in computer vision, and this tutorial will provide you with a solid foundation to build more advanced face recognition and facial analysis applications.

In this tutorial, we focus on detecting faces within an image or video, not identifying or recognizing specific individuals. Always be mindful of privacy and ethical considerations when using face detection or recognition technologies.
