In the past few years, face recognition has received great attention from both research and commercial communities. Areas such as access control using face verification are dominated by solutions developed by both the government and the industry. In this chapter, a face verification solution is presented using open-source algorithms for access control of large-scale events under unconstrained environments. From the type of camera calibration to the algorithms used for face detection and recognition, every stage has a proposed solution. Tests using the proposed solutions in the entrance of a building were made in order to test and compare each solution proposed.
