ISCAS-CLAD is a small dataset of Chinese DLA dataset, of which the layout is annotated with both bounding boxes. The source of the file is an open-source PDF document on the internet. The annotation was generated through pre-labeling and manual correction.
classes:
| Text | Title | Figure | Table | Header | Footer | Reference | Equation |
|---|
The dataset contains a total of 3000 training images and 600 validation images. Each image is associated with a txt and an xml file.
18/April/2022 - released ISCAS-CLAD
Several sample examples and annotation examples are currently provided, and the dataset will be updated continuously in the future.

We added pre-labeling function based on LabelImg. Firstly, the model pre-labels the Bbox with tags, then human correction is applied to the pre-labeled Bbox. Here we provide label files in two formats, YOLO and VOC.
