Description: 为了更有效地提取图像的局部特征,提出了一种基于2维偏最小二乘法(two—dimensional partial least
square,2DPLS)的图像局部特征提取方法,并将其应用于面部表情识别中。该方法首先利用局部二元模式(1ocal
binary pattern,LBP)算子提取一幅图像中所有子块的纹理特征,并将其组合成局部纹理特征矩阵。由于样本图像
被转化为局部纹理特征矩阵,因此可将传统PLS方法推广为2DPLS方法,用来提取其中的判别信息。2DPLS方法
通过对类成员关系矩阵的构造进行相应的修改,使其适应样本的矩阵形式,并能体现出人脸局部信息重要性的差
异。同时,对于类成员关系协方差矩阵的奇异性问题,也推导出了其广义逆的解析解。基于JAFFE人脸表情库的
实验结果表明,该方法不但可以有效地提取图像局部特征,并能取得良好的表情识别效果。-To better the image of the local feature extraction, a partial least squares method based on 2D (two-dimensional partial least
square, 2DPLS) image local feature extraction method, and applied to facial expression recognition. In this method, use of local binary pattern (1ocal
binary pattern, LBP) operator extracts an image texture features of all sub-blocks, and their combination into the local texture feature matrix. As the sample image
Be translated into the local texture feature matrix, so the traditional PLS method can be generalized to 2DPLS method used to extract the identification information. 2DPLS method
Through the class membership matrix in the corresponding modifications to adapt the sample matrix, and can reflect the importance of face poor local information
Different. Meanwhile, members of the class covariance matrix of the singular relations issues, also derived the generalized inverse of the analytical solution. Based on the JAFFE facial expression database
