感谢作者团队提供的宝贵的三时相SCD数据集!我在观察样本时,没有搞清楚SCD标签的标注规则,以HS15_0.tif、HS16_0.tif、HS18_0.tif 为例,绿框中内容,1516的scd标签中变化部分的语义标注的是15时相的语义类别,但在1618的scd标签中变化区域的标签却是新的语义类别,数据集readme中并未进行介绍。对此非常疑惑,希望能得到您的解答!再次感谢!

您好,感谢您的提问!语义变化的标签具体查看其编号即可。根据上色规则,语义变化的颜色会与前一时相的语义类别颜色色系相近。因此1516的语义变化部分颜色接近于15年语义类别,1618的语义变化部分颜色接近于16年语义类别。

感谢解惑!那是不是就是理解成:SCD标签中像素的语义类别,表示的是from to对吗?比如我给的图中绿框内,表示excavation(紫色)变为regetation(绿色)
