  • 100 RGB images per sign (total 47 signs) from each of 10 users
  • Total input images : 100×47×10 = 47000
  • Input images are processed via MediaPipe, which provided
    • an output image with hand key-points being detected
    • 3D coordinate values of 21 predefined key-points
    • Total 63 coordinate values for each sample
  • The values are stored in csv files
  • 1 CSV file contains values from 100 samples of 1 sign from 1 user
  • Total CSV files : 47×10 = 470

The dataset has been made public for further research purposes. It is also available upon request here.
