Paper Abstract

A method combined Kernel Principal Component Analysis (KPCA) with BP neural network is proposed for multispectral remote sensing image classification in this paper. Firstly, the KPCA transformation including Gaussian KPCA and polynomial KPCA is carried out to get the former three uncorrelated bands containing most information of the TM images with seven bands. Secondly, BP neural network classification is executed using the three bands data after KPCA transformation. For testifying, both the classical PCA and the KPCA are applied to the multispectral Landsat TM data for feature extraction. The results demonstrate that the method proposed in this paper can improve the classification accuracy compared with that of principal component analysis (PCA) and BP neural network.
