The CPMS dataset is a camera-based printed music score dataset under realistic scenarios created by us, which is set up by taking photos with mobile devices under different angles and light conditions. The test set is originate from the public repertoire of the 2020 sight-singing exam at the Wuhan Conservatory of Music in China(http://www.hbea.edu.cn/html/2019-09/12349.html), and we take pictures and label the printed msuic scores.
Our project adopts the following directory structure
CPMS_Dataset/
├── data/
| ├── IMG_1609.jpeg
| ├── IMG_1610.jpeg
| └── ...
├── label/
| ├── IMG_1609.json
| ├── IMG_1610.json
| └── ...
The data folder stores the pictures of the photographed music scores, and the label folder stores the annotation data. Each music score image corresponds to a json format label.
