Face detection or the Haar classifier

The Haar classifier builds a boosted rejection cascade, and it can be used to detect faces of other rigid objects. As seen in the preceding table, the Haar classifier is not included in Emgu.CV.ML but it is a machine-learning algorithm. The computer vision field changes very fast and some parts of the library are implemented individually, to reduce the risk of running out of data. Face detection techniques advance with time and as we see, the HaarCascade class is obsolete so we are going to study the CascadeClassifer class.

In OpenCV and Emgu CV, the first implementation of the face detection technique was developed by Paul Viola and Michael Jones, and later extended by Jochen Maydt and Rainer Lienhart. The ...
