Table 3
The comparison with the image-based method in COAD dataset.
| Methods | Symbols | Top 1 (%) | Top 3 (%) |
| Image-based [5] | Partially drawn symbols | 54.94 | 97.08 | Fully completed symbols | 79.83 | 99.27 |
| Proposed | Partially drawn symbols | 83.57 | 98.90 | Fully completed symbols | 75.60 | 85.53 |
