Slant Discriminant Analysis for Image Feature Extraction
Liyan Zhao, Dong Zou, Guanghong Gao · 2013
In this paper, a novel feature extraction algorithm,called Slant discriminant analysis (SDA), is proposed. SDA aims to use the relation of rows and columns of image samples to extract the directional feature of the image samples. The proposed algorithm is applied to image classification on Yale face Database.The experimental results demonstrate the effectiveness of the proposed algorithm.
