针对海量的高光谱遥感图像光谱和丰富的空间信息中可用于分类的有标记样本远少于无标记样本的数据特性,提出了一种融合光谱度量标记迁移和Tri-training的高光谱遥感图像半监督光谱-空间分类算法。该算法提出了一种基于光谱度量的标记迁移方法,通过结合迁移标记和Tri-training预测标记进行扩充样本标记预测,提高了扩充样本标记的准确性。同时,该算法基于空间相关性选择扩充样本,综合运用光谱和空间特征提升图像分类的精度。在两个公开的高光谱遥感图像数据集上进行了实验,结果表明该算法优于基于Tri-training算法的高光谱遥感图像的分类性能。
Aimed at the problem that a large number of hyperspectral remote sensing images were rich in spectral and spatial information
and the labeled samples available for image classification were far less than unlabeled samples
a semisupervised spectral-spatial classification algorithm was proposed by fusing spectral measure-based label transfer and Tri-training.A spectral measure-based label transfer method was proposed for our algorithm.The transferred labels and predicted labels for Tri-training algorithm were used to predict the labels of expanded unlabeled samples
which can promoted the prediction accuracies of labels for expanded unlabeled samples.Meanwhile
our algorithm selectel expanded samples based on spatial correlation
and used spectral and spatial features to improve the accuracy of image classification.Experimental study was executed on two public hyperspectral remote sensing image datasets
and the results showed that the proposed algorithm outperform tri-training algorithm.
