This dataset contains alphanumeric characters, Greek characters and mathematical symbols . All symbols in this dataset are extracted from "CROHME: Competition on Recognition of Online Handwritten Mathematical Expressions dataset"
For representing symbols as images following processes have been done:
- Conversion from INKML to PNG
- Margin removal
- Resizing based on Aspect Ratio
- Short 64x48
- Square 64x64
- Tall 48x64
- Slim 16x48
In addition, for non-alphanumeric symbols synthetic symbols were generated by distortion.
