1. A real-time face recognition apparatus comprising: a face detector configured to detect a face image by obtaining image coordinates of a face from an input image; a facial feature extractor configured to generate feature histogram data based on parallel processing from the face image detected by the face detector, wherein the facial feature extractor comprises a convolution filtering operation processor configured to access pieces of image data from the face image using a window, wherein the window has a width of one pixel and a length identical to that of Gabor filter pairs used to filter the face image; a database (DB) configured to store predetermined comparative feature histograms; and a histogram matcher configured to compare the histogram data generated by the facial feature extractor with the comparative feature histograms stored in the DB, and then output similarities of the face image.
