Abstract

The invention discloses a handwriting recognition method and a device, which can be used for recognizing a character string which is continuously input by the handwriting of a user so as to provide convenience for the user. The method comprises the following steps: calculating various characteristics of the inputted character string, such as accuracy characteristic and space geometrical characteristic for recognizing the individual character of various stroke combinations; calculating the cutting credibility of each stroke combination in various cutting modes by using a probability model, wherein the coefficients in the probability model are estimated by training the existing sample by using a parameter estimation method; in the process of recognizing the individual character of stroke combinations, recognizing the characters with different writing methods by using a multiple-template matching method; searching out the optimal cutting route; and optimizing the recognition result by performing postprocessing. The method and the device of the invention have the advantages of simple structure, low hardware requirement, high recognition speed, high identification rate and the like, and can be realized in an embedded system and the like.

Description

technical field [0001] The invention relates to character input, in particular to a handwriting recognition method and device, capable of recognizing multiple frameless characters continuously handwritten by a user and improving input efficiency. Background technique [0002] Currently, modules capable of recognizing user's handwriting input are widely used in electronic devices such as mobile phones, which enables users to interact with electronic devices without having to learn other input methods for character input through keys. [0003] Non-Patent Document 1 ("Online Character Segmentation Method for Unconstrained Handwriting Strings Using Off-stroke Features" (Source: Hitachi Ltd. in the Tenth International Workshop on Frontiers in Handwriting Recognition, La Baule, France, 2006)) discloses a handwriting Recognition methods, which devise physical features ('off-stroke' features) of segmented patterns to recognize character sequences of frameless handwritten input. In ...
