The following work focuses on the tracking process for obtain face detection and tracking of faces, as part of the computer vision. To complete this study, the tracking and facial recognition process by the software tool MATLAB and the Viola-Jones algorithm will be developed. Once the codification has been developed, the results are assessed and the performance of the created script has been verified. Also an important factor for mention is the control of rate error of the false faces recognition. Also we show a methodology for evaluate the algorithms efficiency. Finally the different conclusions are made in relation the results obtained.
