Face Recognition Using Dual-Tree Complex Wavelet Features
Chao-Chun Liu, Dao‐Qing Dai · IEEE Transactions on Image Processing · 2009
We propose a novel facial representation based on the dual-tree complex wavelet transform for face recognition. It is effective and efficient to represent the geometrical structures in facial image with low redundancy. Moreover, we experimentally verify that the proposed method is more powerful to extract facial features robust against the variations of shift and illumination than the discrete wavelet transform and Gabor wavelet transform.
