Abstract
A method and an apparatus for capturing facial expressions are provided, in which different facial expressions of a user are captured through a face recognition technique. In the method, a plurality of sequentially captured images containing human faces is received. Regional features of the human faces in the images are respectively captured to generate a target feature vector. The target feature vector is compared with a plurality of previously stored feature vectors to generate a parameter value. When the parameter value is higher than a threshold, one of the images is selected as a target image. Moreover, a facial expression recognition and classification procedures can be further performed. For example, the target image is recognized to obtain a facial expression state, and the image is classified according to the facial expression state.
