Feature extraction is one of the key steps of face recognition. It first outlined the basic models and principles of the independent component analysis ( ICA) and described the general process of using fast independ?ent component analysis ( FastICA) for feature extraction. Then gave a parallel computing algorithms of FastICA for separation matrix. At last, it conducted a simulation experiment using ORL face image database in Matlab environ?ment. The experimental results show that, this method of FastICA is an effective method for feature extraction. In addition, it also discussed several factors that affect the classification and recognition in the end.
