| 摘 要： | 二阶局部导数模式是一种基于一阶局部导数变化的方向性编码方式.相对于局部二值模式,二阶局部导数模式能够提取出图像的更多细节信息.本文提出了一种融合Gabor特征二阶局部导数模式的人脸识别方法,该方法首先利用Gabor滤波良好的空间位置与方向选择特性,采用四个频率六个方向的Gabor滤波器对图像进行滤波.其次,利用数据的类...

| Abstract: | Second-order Local Derivative Pattern (LDP) is a general framework to encode directional pattern features based on local first-order derivative variations.Different from Local Binary Pattern (LBP),the second-order derivative pattern extracts local information by encoding various distinctive spatial relationships contained in a given local region and thus it can capture more detailed information than the first-order local pattern used in LBP.A new algorithm based on Fusion of Second-order Local Derivative Pa... |
