1. A rapid facial recognition system, for performing recognition according to a plurality of classes, comprising: at least an image capture device used for capturing a facial image; a plurality of response recognition computing units, each of which further comprising: a second feature recognition module having a part of the plurality of classes performs rapid facial recognition in accordance with a set of feature data and the part of the plurality of classes allocated to the second feature recognition module for generating a second recognition result as a response; and at least a broadcasting feature computing unit connected to the plurality of the response recognition computing units via the network, further comprising: a first feature recognition module having the other part of the plurality of classes, performs rapid facial recognition in accordance with the set of feature data and the other part of the plurality of classes allocated to the first feature recognition module for generating a first recognition result as a response; a first feature extraction module used for extracting features of the facial image to generate the set of feature data and further broadcast the set of feature data to the first feature recognition module and the plurality of second feature recognition modules; and a first identification module used for identifying the first recognition result and the plurality of second recognition results to accomplish the recognition of an individual's identity; wherein the plurality of response recognition computing units are divided into a plurality of groups in accordance with the distance between the plurality of response recognition computing units and the broadcasting feature computing unit; and the broadcasting feature computing unit broadcasts the set of feature data to the nearest group first, and if the recognition fails, then the broadcasting feature computing unit broadcasts the set of feature data to the next nearest group until the second feature recognition module of one of the plurality of response recognition computing units is successful in face recognition, or the first feature extraction module has finished broadcasting to all the plurality of groups.
