Therefore, // faces that are turned too far won't be detected under fast mode. // // For front facing mode only, the detector will use the "prominent face only" setting, // which is optimized for tracking a single relatively large face. This setting allows the // detector to take some shortcuts to make tracking faster, at the expense of not being able // to track multiple faces. // // Setting the minimum face size not only controls how large faces must be in order to be // detected, it also affects performance. Since it takes longer to scan for smaller faces, // we increase the minimum face size for the rear facing mode a little bit in order to make // tracking faster (at the expense of missing smaller faces).

The only difference // between these cases is the choice of Processor: one that is specialized for tracking // a single face or one that can handle multiple faces.
