Kernel PCA in Detecting Moving Vehicle from Its Viewpoint

Kernel principal component analysis (KPCA) has gained much attention for capturing nonlinear image features which is particularly important for clustering high-dimensional multi-class features. We introduce KPCA in this paper for detecting and classifying moving vehicles from its viewpoint images. The KPCA extracts non-linear features of multi-class moving vehicles by mapping input space to a higher dimensional feature space through a nonlinear map. The results provide us a clustered feature space of the car and non-car for classifying them by separating the dimensional space or eigenvector. The experimental results show the robustness of the KPCA´s feature separation in our car database that lead to the cars´ classification. Extended experiments on various vehicles detection have also shown the remarkable performance of the proposed method
