It’s all about openCV

Open Source Computer Vision is a popular library started by Intel in 1999. This library sets its focus on real-time image processing and includes patent-free implementations of the latest computer vision algorithms.

OpenCV now comes with the very new Face Recognizer class for face recognition, so you can start experimenting with face recognition right away. It shows you how to perform face recognition with Face Recognizer in OpenCV and gives you an introduction into the algorithms behind.

Checkout the difference between two images and their code:

The currently available algorithms are:

• Eigenfaces (see EigenFaceRecognizer::create)
• Fisherfaces (see FisherFaceRecognizer::create)
• Local Binary Patterns Histograms (see LBPHFaceRecognizer::create)
