Real-Time Face Landmark Detection OpenCV Python Source Code

The Real-Time Face Landmark Detection OpenCV Python was developed using Python OpenCV, Face detection is a computer technology being used in a variety of applications that identifies human faces in digital images. Face detection also refers to the psychological process by which humans locate and attend to faces in a visual scene.

A Face Landmark Detection OpenCV Python is the process of detecting landmarks or regions of interest (key-points) on the face like Eyebrows, Eyes, Nose, Mouth. In this article the system can detect the face of the human in real-time using web camera.
