你好,我观察了下数据集中的标注数据。有些图片标注的似乎不是很精细;
有些图片,道路中的forest会一起被标注为道路;
有些图片中的建筑物会出现漏标,只标一部分;
有些图片中的建筑物还会把周围比较多的背景包括进去;
有些图片中占比较小的forest会被漏标,有些图片又会标记这些较小的forest。
如 Val/Urban/3518 建筑物只标注了一部分 Val/Urban/3532
请问,Test 数据集中的标注也会出现这样的情况吗?还是 Test 数据集中的标注比 Train 和 Val 的要更精细一些。

感谢您指出标注存在了一些问题,目前来看,这些细碎的问题不影响大数据驱动下的模型训练。 可以参考MMCV给我们数据集Benchmark的结果。 (open-mmlab/mmsegmentation#1006 (comment))
测试集是我们仔细检查过的,应该错误会少一些。我们也正在整理收集现有标注错误,希望您也可以协助我们,上传给我们修改后的正确标注,我们也会有进一步的更新。
