HWR (Handwriting Recognition) method and HWR system of single Chinese character

Abstract

The invention relates to an HWR (Handwriting Recognition) method of a single Chinese character, which is used for a terminal with a handwriting recognition function. The HWR method comprises the following steps of obtaining an initial of phonetics of a Chinese character input through a virtual keyboard of a touch screen or the initial of the phonetics of the Chinese character input through a handwriting input recognition area of the touch screen; recognizing the obtained initial, using the obtained initial as an alphabet code and prefetching the Chinese character in from a pre-store Chinese character library according to the alphabet code; obtaining strokes of the Chinese character input through the handwriting input recognition area of the touch screen; recognizing the obtained strokes and using the obtained strokes as a stroke code; and searching the Chinese character having the stroke code in the pre-store Chinese character library according to the recognized stroke code, displaying a Chinese character selecting option on the touch screen, confirming information according to the option of a user and displaying a selected Chinese character. The invention also relates to an HWR system of the single Chinese character. According to the HWR method and the HWR system, disclosed by the invention, the phonetic input and the stroke input are combined, the input efficiency is increased, and the success rate of input recognition is increased through reducing the input of handwriting strokes and phonetic alphabets.

Description

technical field [0001] The invention belongs to the field of Chinese character recognition, in particular to a single Chinese character handwriting recognition method and system.
