Problems solved by technology

For example, if the user wants to input "we", the input process requires the user not to overlap the phrases to be written, so the continuous input of phrases requires a relatively large input area on the screen, which is easily limited by the screen size

Embodiment Construction

[0028] figure 1 Show the method flow of handwriting recognition in the present invention, comprise the following steps:

[0029] In step S10, a character library is established, and a phrase comparison feature set and a word comparison feature set are respectively extracted from the phrases in the font library and the individual characters forming the phrases. In one embodiment, in the initial process of handwriting recognition, according to need, import phrase and the individual character that forms phrase, set up font, and extract phrase comparison feature set one by one to this phrase in the font, to form the individual character of this phrase one by one One extracts the character comparison feature set, so that it is no longer necessary to re-establish the font library in the subsequent recognition process, and the phrase comparison feature value and the word comparison feature value and the word comparison feature set recorded in the word comparison feature set and the w...

Abstract

The invention provides a method for identifying handwriting. The method comprises the following steps: establishing a font library, and respectively extracting a phrase comparison characteristic set and a single word comparison characteristic set on phrases and single words which form the phrases in the font library; and receiving handwriting data; segmenting and identifying the handwriting data according to the phrase comparison characteristic set and the single word comparison characteristic set of each single word in the phrase when the receiving is complete. According to the handwriting identifying method, the phrase input by a user can be identified by segmenting the handwriting data overlaied in the handwriting data input by user handwriting and comparing with the single word and phrase comparison characteristic sets in the font library, and stroke overlaid phrases are identified, so that the handwriting input is not limited by screen size any more, handwriting can be continuously overlaid, and the input efficiency of user handwriting is improved.

Description

【Technical field】 [0001] The invention relates to handwriting recognition technology, in particular to a handwriting recognition method and system. 【Background technique】 [0002] Traditional phrase handwriting recognition is divided into single character input recognition and phrase continuous input recognition. Single-character input recognition means that after writing a complete character track with a finger or a stylus, pause for a certain time interval. If the time interval expires, the writing is completed, and then track recognition is performed. After selecting the correct recognition candidate result, continue Do follow-up writing. The single-character input recognition can be applied to full-screen handwriting or writing in a designated area. For example, if the user wants to input the phrase "we", the user first writes the track of the word "I", pauses for a certain time interval, recognizes "I", and then continues to write "we", and so on. until the end.
