| Abstract(in English) | We propose an adaptive discriminant space that is constructed from the candidates' facial images optimally distinguishes between faces among certain candidates. First, our method chooses the candidates using a hierarchical combination of face direction estimation and recognition using the Four-Directional Features based on Linear Discriminant Analysis. Next, face direction is estimated exactly by each candidate's discriminant space of face direction estimation. Finally, our method creates a new discriminant space from the candidates' facial images selected from the results of the face direction estimation procedure. Using the adaptive discriminant space, the candidates can be selected optimally. Experiments showed that our method improved our accuracy rate 1.2% to 98.8%, achieved by hierarchical face recognition of 105, 000 images from 150 subjects facing 35 different directions. |
