Abstract:
1. A face recognition apparatus adapted for recognizing an input face image based on one or more registered face images, comprising: a face image inputting unit that inputs the face image to be recognized; a Gabor filter application unit, implemented via a processor, that calculates convolution of a pixel value at each feature value extraction position of the input image and coefficients of a Gabor filter, the coefficients of the Gabor filter being defined by a Gabor function representing a spatial characteristic using a Gaussian function representing a window and a sine function or a cosine function representing a frequency response, for each of a predetermined set of frequency values and for each of a predetermined set of angles of a response function of the Gabor filter thereby determining a Gabor jet having as many scalar values as there are Gabor filters; a similarity calculation unit an identification determination unit that determines when the input face image is identical to the registered face image based on the similarity vector, the Gabor filter application unit including
