This repository mainly consists of two parts: five files starting with syncG, which are the synthetic meter dataset, and the scene_file folder, which contains the scene files used for data generation.
For more detailed instructions on data generation, please visit: https://github.com/SKYWOWDYH/SyncG
Due to the large file size, the data files have been compressed into multiple volumes. We recommend downloading all files starting with syncG to the same directory and then unzipping them using the following commands in that directory:
zip -s- syncG.zip -O syncG_full.zip
unzip -q syncG_full.zip
After extraction, the dataset directory structure will be as follows:
syncG/
|-- annotations/
| |-- test/
| |-- train/
|-- images/
| |-- test/
| |-- train/
|-- masks/
|-- test/
|-- train/
