OpenCV (Open Source Computer Vision Library) is an open-source computer vision and machine learning software library. OpenCV was built to provide a common infrastructure for computer vision applications and to accelerate the use of machine perception in the commercial products. Being a BSD-licensed product, OpenCV makes it easy for businesses to utilize and modify the code.
Building a program that detects and recognizes faces is a very interesting and fun project to get started with computer vision.
Face Detection is the process of detecting faces, from an image or a video that doesn’t matter. The program doesn’t do anything more than finding the faces. But on the other hand, face recognition, the program that finds the faces and also it can tell which face belongs to who. So it is more informational than just detecting them.
