First, facial image from camera is exacted to compute facial shape and texture model using active appearance model (AAM). Second, we use modified Lucas-Kanade image alignment algorithm to find facial features. Third, the texture model of AAM is used to construct facial texture parameters. These parameters are used to train a back propagation neural network (BPNN) for face and facial expression recognition. In recognition process, we first use face recognition to find user’s identity; then we use recognized user’s facial expression database to recognize his/her facial expression. In experiments based on BU-3DFE database, a face recognition rate of 98.3% has been achieved. The facial expression recognition rate of the proposed integrated method (using a personal facial expression classifier) is 83.8%. It is a great improvement compared with using conventional facial expression classifier of 69.6%. Song, Kai-Tai 宋開泰 2010 學位論文 ; thesis 87 zh-TW |
