摘要 文章提出了一种人脸表情识别的新方法。利用光流技术对人脸表情图像序列中的特征点进行跟踪,并提取特征向量。最后,利用神经网络对六种基本表情进行分类识别。 A new technique for facial expression recognition is proposed, which uses optical flow to automatically track feature points in the image sequence, eigenvectors are extracted from the optical flow. Neural network is used to classify the facial expression.
