Example Embodiment

[0092] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and implementation manners.

[0093] Such as figure 1 What is shown is a flow chart of a handwriting recognition method according to an embodiment of the present invention, which includes the following steps:

[0094] Step 101: Obtain character handwriting.

[0095] The acquisition of the character handwriting may be the character handwriting input by the user acquired online in real time, or it may be the character handwriting acquired offline through image recognition technology, which is not limited in the embodiment of the present invention.

[0096] In addition, the character handwriting may be a character handwriting input in a row, such as Western, or a character handwriting input in a column, for example, the writing habit o...

Abstract

The invention discloses a handwriting recognition method and device. The method comprises the steps that character handwriting is acquired; obtaining a segmentation model corresponding to the languagecategory to which the character handwriting belongs; segmenting the character handwriting by using the segmentation model to obtain a segmentation block sequence; and identifying the segmentation block sequence to obtain a character string corresponding to the character handwriting. By utilizing the method and the device, relatively high recognition accuracy can be achieved under the condition ofrelatively few data resources.

Description

technical field [0001] The invention relates to the field of handwriting recognition, in particular to a handwriting recognition method and device. Background technique [0002] Handwriting recognition technology refers to the process of converting the ordered trajectory information generated when writing on a handwriting device into a text internal code. In fact, it is a mapping process from the coordinate sequence of the handwritten trajectory to the internal code of the text. One of the natural and most convenient means. With the popularization of intelligent terminals such as smart phones and PDAs, handwriting recognition technology has also entered the era of large-scale application. [0003] Since languages ​​in different countries have different writing characteristics, the existing handwriting recognition technology for a single language cannot realize the recognition of handwritten texts in other languages ​​well. To this end, the industry has proposed some techni...
