摘要
Abstract
An infrared target recognition method based on covariance descriptor and kernel sparse coding is proposed in this paper. Covariance descriptor combining infrared image gray intensity values and the norm of first and second order derivatives of the intensities as infrared image features. With respect tox andy is extracted as feature representation, similarity of covariance descriptors is computed through Log-Euclidean metric. Then covariance descriptors are mapped into a high dimensional feature space through Gaussian kernel function. Finally, infrared target recognition is accomplished using sparse coding in the new feature space. Experiments on the real infrared images show that our method obtains better results compared with traditional algorithms such as KNN and SVM.关键词
