Abstract :
A handwritten Chinese character generator that generates handwritten Chinese characters with different variations is proposed and used for evaluating the performance of an OCR system. The character generator first generates radicals of a character stroke by stroke and then combines the generated radicals to form a line-vector character. Then, the line-vector character is thickened to obtain a character image. The generated characters are then used to evaluate the stability of stroke extractors and calculate the peak performance of a matching module and the recognition error caused by stroke extractors
