Is there a Python face recognition demonstration?

OpenCV is an open source cross-platform computer vision library, which provides interfaces for languages such as Python and implements many common algorithms in image processing and computer vision.

Opencv has built-in Harr classifier based on Viola-Jones target detection framework, which can directly call detectObject to complete the detection process by loading a configuration file (Haar Cascade _ Frontalface _ alt.xml), and also supports the detection of other features (such as nose, mouth, etc.). ).
