OpenCV is an open source computer vision and machine learning software library. It is a BSD-licence product thus free for both business and academic purposes.The Library provides more than 2500 algorithms that include machine learning tools for classification and clustering, image processing and vision algorithm, basic algorithms and drawing functions, GUI and I/O functions for images and videos. Some applications of these algorithms include face detection, object recognition, extracting 3D models, image processing, camera calibration, motion analysis etc.
OpenCV is written natively in C/C++. It has C++, C, Python and Java interfaces and supports Windows, Linux, Mac OS, iOS, and Android. OpenCV was designed for computational efficiency and targeted for real-time applications. Written in optimized C/C++, the library can take advantage of multi-core processing.
Face detection has gained a lot of attention due to its real-time applications. A lot of research has been done and still going on for improved and fast implementation of the face detection algorithm. Why is face detection difficult for a machine? Face detection is not as easy as it seems due to lots of variations of image appearance, such as pose variation (front, non-front), occlusion, image orientation, illumination changes and facial expression.
In this project, we used medapipe, an open source Python library for detecting and tracking faces. To make it more accessible, we deployed it on the internet using Heroku. For the backend, we used Flask, and for the front end, we used Bootstrap and HTML. You can check the deployment here !
