摘要: 从影像特征相似性出发研究基于Landsat-8影像相似性的智能解译样本动态制备方法,构造光谱相似度、纹理相似度、空间邻近度3种样本集选择方法。基于相同的U-Net+EfficientNet-B3语义分割网络,对比了根据3种测度下选择的样本影像所制备的样本集对总体分类精度的影响。结果表明,从历史成果数据中选择样本影像用于模型训练,是提高分类精度的有效方法;在3种样本影像选择策略中,空间邻近度可得到精度最高、方差最小的分类结果;历史成果数据中的错误标签会导致智能模型精度降低。

Abstract: A dynamic preparation method for intelligent interpretation samples based on Landsat-8 image similarity was studied from the perspective of image feature similarity. Three sample set selection methods were constructed, including spectral similarity, texture similarity, and spatial proximity.Based on the same U-Net+EfficientNet-B3 semantic segmentation network, the impact of sample sets prepared from selected sample images under three measures on overall classification accuracy was compared. The results indicated that selecting sample images from historical achievement data for model training was an effective method to improve classification accuracy;among the three sample image selection strategies, spatial proximity could obtain the classification results with the highest accuracy and the lowest variance;incorrect labels in historical achievement data could lead to a decrease in the accuracy of intelligent models.
