摘要
讨论了静态图像表情特征提取方法,提出了一种基于图像差分法的人脸表情识别方法。通过差值图找到特征点,采用特征点拟合的办法找出特征区域的变化,通过Matlab验证了该方法的可行性。
This paper discusses the static image feature extraction methods.Presents a method that based on the difference image method of facial expression recognition.Through difference image to find the feature points,and use the toolboxes in MATLAB to fit the feature points in order to find the change with feature region.Through the experiment,verify the feasibility of the method.
