CROHME: Competition on Recognition of Online Handwritten Mathematical Expressions (PNG)

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 Slim 16x48 In addition, for non-alphanumeric symbols synthetic symbols were generated by distortion.
