OCR

The jadeocr OCR API is at the heart of what jadeocr was made to do: help language learners practice their handwriting.

Handwriting Recognition

The handwriting recognition API handles detecting handwriting in Simplified Chinese, Traditional Chinese, and Japanese.

Preparing the data

The handwriting recognition API works on a stroke array, which can be generated with an HTML canvas or similar tools. Send the array as a string in the request.

Here is a sample stroke array for the character "口":

Copy
[[(75,128),(83,172),(85,196)],[(84,127),(91,124),(123,121),(151,121),(161,121),(161,128),(165,157),(164,181),(162,195)],[(89,187),(103,194),(129,200),(149,199)]]
