1. A computer-implemented method of performing face detection using parallel analysis, the method comprising: selecting, using a processor, a plurality of locations within an image; determining, for each selected location in parallel, a classifier score for each of a plurality of classifiers associated with an analysis stage; combining, for each selected location, the classifier scores for the plurality of classifiers to generate a total classifier score associated with the analysis stage; comparing, for each selected location, the total classifier score to a threshold; and generating a classifier mask based on the comparison of the total classifier score and the threshold for each of the selected locations.
