A practical implementation of face detection by using Matlab cascade object detector

The detection of faces in an image is a subject often studied in computer vision literature. The algorithm which allowed face detection, imposing new standards in this area, was the Viola - Jones algorithm. In this paper, a practical implementation of a face detector based on Viola-Jones algorithm using Matlab cascade object detector is presented. Employing the system type object vision.CascadeObjectDetector, eight face detectors were developed using the trainCascadeObjectDetector function and tuning the number of cascade layer and the False Alarm Rate. For different tuning parameters, the performances of the face detectors were analyzed.
