Problems solved by technology

Among them, the LSTM method requires a large amount of data training to obtain a better convergence result, and requires a large amount of computing resources and training time to obtain a better word accuracy rate (the word accuracy rate will be reduced correspondingly); while the HMM-based method Although it can effectively solve the problem of continuous strokes in cursive script, this method is very difficult in the process of feature extraction, and feature extraction directly affects the final model effect

Embodiment Construction

[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 in conjunction with the drawings and implementations.

[0093] Such as figure 1 Shown, is a kind of flowchart of the handwriting recognition method of the embodiment of the present invention, comprises the following steps:

[0094] Step 101, acquire character handwriting.

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

[0096] In addition, the character handwriting can be character handwriting input continuously in rows, such as Western characters, or character handwriting input continuously in columns. For example, th...

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...
