Abstract: | A novel cascade face recognition system using hybrid feature extraction is proposed. Three sets of face features are extracted. The merits of Two-Dimensional Complex Wavelet Transform (2D-CWT) are analyzed. For face recognition feature extraction, it has proved that 2D-CWT compares favorably with the traditionally used 2D Gabor transform in terms of the computational complexity and features? stability. The proposed recognition system congregates three Artificial Neural Network classifiers (ANNs) and a gating network trained by the three feature sets. A computationally efficient fitness function of the genetic algorithms is proposed to evolve the best weights of the ensemble classifier. Experiments demonstrated that the overall recognition rate and reliability have been significantly improved in both still face recognition and video-based face recognition. |
