- Abstract:
-
To remove the redundancy of selected samples in the multiview active learning classification of hyperspectral images and reduce the cost of manual marking, this paper proposes two methods for the selection of diverse samples in the multiview active learning classification. First, hyperspectral images are divided into superpixel segments, then samples belonging to different superpixel segments are added to the training set, and the remaining samples are put back into the candidate set. Second, the prediction labels of the samples from each view are compared, then the samples with different prediction labels are added into the training set, and the remaining samples are put back into the candidate set. In this study, the two methods are used to improve the sample selection method in the traditional multiview active learning classification, and experiments are conducted in two groups of hyperspectral image data. The results show that the accuracy of classification is unchanged, yet the number of training samples is greatly reduced after using the two methods.
