Abstract: The traditional hyperspectral remote sensing image classification is limited by the number of training samples,so it is difficult to obtain the better classification results.This paper proposes a hyperspectral remote sensing image classification method based on semi-supervised support vector machine of clustering kernel.The method constructs a kernel matrix to obtain more excellent classifier by semi-supervised support vector machine and unlabeled sample,and improves classification accuracy based on small sample.The experimental results show that the classification accuracy of this method proposed in this paper is better than the traditional method,and has good stability.

Key words: hyperspectral remote sensing image, S3VM model, unlabeled sample, semi-supervised classification
