资源简介：
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
Categorization:
Short 64x48
Square 64x64
Tall 48x64
