+- [PubLayNet dataset](#publaynet)
+- [CDLA dataset](#CDLA)
+- [TableBank dataset](#TableBank)
+
+
+Most of the layout analysis datasets are object detection datasets. In addition to open source datasets, you can also label or synthesize datasets using tools such as [labelme](https://github.com/wkentaro/labelme) and so on.
