| 摘 要： | 介绍了面部表情识别的主要步骤，在此基础上提出了一种多姿态多状态的面部情绪模型．该系统利用图像质量的评价结果来决定面部检测的方法，通过中性脸的检测来实现表情边界的分割，从而把提取的表情运动特征参数作为BP神经网络的输入，进而实现面部表情的识别．实验表明，该系统具有很好的识别效果．

| Abstract: | The primary steps of facial expression recognition were introduced; the multi pose and multi state facial emotion models were proposed. The method of face detection by using the result of image quality estimation was selected. Segmentation of expression border was realized by the detection of neural face. By taking the feature parameters of the extracted expression motion as the input of BP neural network, the facial expression was recognized. The results showed that the system was characterized by good recognition. |
