【摘要】 在人脸表情的识别中,动态表情图像包含丰富的信息,应用非常广泛.在动态表情特征的提取中,差图像特征提取是通过基于逆向组合的图像对齐方法实现的,图像对齐方法可以在一定程度上避免差图像特征与几何特征的误差相关性,同时逆向组合又可以保证在不损失图像对齐精度的前提下大大提高运算速度.更多还原

【Abstract】 During the course of facial expression recognition,dynamic expression image includes fruitful information and is used widely.During the extraction of dynamic features of expression,the extraction of different images can be realized by reversing compositional method of image alignment,the method of image alignment can avoid the conflict between the features in different image and geometric features.Moreover,reverse composition will double the calculating speed without doing harm to the images.更多还原
