Converting English Hand-Drawn Chars74k Data to JSON
You can download the JSON-converted files directly. The JSON object maps each letter in the dataset (0-9, a-z, A-Z) to a list of letterforms (55 for each letter), which in turn are lists of strokes, which are lists of [x, y] coordinates for each point in the stroke.
- Normalized (translated so that each letterform is centered on the center of the strokes' bounding box)
Here's an example of the data in use.
