Embodiment 1

[0026] figure 1 It is a flow chart of the character recognition method in Embodiment 1 of the present invention, and this embodiment is applicable to the situation where an electronic notebook recognizes handwritten input characters. The method can be executed by a text recognition device, and the text recognition device can be implemented in software and / or hardware, for example, the text recognition device can be configured in a server. Such as figure 1 As shown, the method specifically includes:

[0027] S110. Obtain image and text information to be identified.

[0028] In this embodiment, the image-text information to be recognized is text information that needs to be recognized. Optionally, the format of the text information to be recognized may be a picture format. For example, when the user needs to input text on the electronic device by handwriting, the user can input text by sliding on the touch screen of the electronic device through an input device (such as a to...

Embodiment 2

[0045] figure 2 It is a flow chart of the character recognition method in Embodiment 2 of the present invention, and this embodiment is further optimized on the basis of the foregoing embodiments. Such as figure 2 As shown, the method includes:

[0046] S210. Obtain image and text information to be identified.

[0047] S220. Obtain identification information corresponding to the user to which the graphic-text information to be identified belongs.

[0048] In this embodiment, in order to more accurately identify the text information input by the user, before identifying the graphic information to be recognized, it is necessary to determine the user currently inputting the text. Optionally, the identification information (such as user name) of the current user can be determined by obtaining the user's login information; it is also possible to analyze the operation mode of the current user when the user operation is detected, and compare the current user operation mode with ...

Embodiment 3

[0057] image 3 It is a flow chart of the character recognition method in Embodiment 3 of the present invention, and this embodiment is further optimized on the basis of the foregoing embodiments. Such as image 3 As shown, the method includes:

[0058] S310. Acquire an original text and a standard text corresponding to the original text, and use the original text and the standard text as text training samples for a feature point extraction model to be trained.

[0059] In this embodiment, prior to character recognition of the image-text information to be recognized, it is necessary to carry out personalized training on the feature point extraction model.

[0060] Optionally, first establish a feature point extraction model to be trained corresponding to the user identifier, and prompt the user to input text training samples for the feature point extraction model, so as to obtain text training samples for the feature point extraction model. For example, obtain the original ...

Abstract

The embodiment of the invention discloses a character recognition method and device, a server and a medium. The method comprises the steps that graphic and text information to be recognized is acquired; through a pre-trained characteristic point extraction model corresponding to a user to who the graphic and text information to be recognized belongs to, characteristic points of the graphic and text information to be recognized are extracted from the graphic and text information to be recognized; the characteristic points are matched with character characteristic points in a pre-established character library, and characters corresponding to the graphic and text information to be recognized are determined. According to the embodiment, the personalized characteristic point extraction model isused for extracting the more accurate characteristic points of the graphic and text information to be recognized, according to a current operation, the user accurately recognizes the characters whichare input in an electronic notebook through handwriting, then the user executes more operations conveniently, and the user experience is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of information technology, and in particular, to a character recognition method, device, server and medium. Background technique [0002] With the development of smart electronic products, traditional paper-based data has gradually moved towards electronicization. Because electronic data is easy to store and carry, traditional paper-based data has gradually been replaced by electronic data, and has gradually evolved into the use of electronic devices for data processing. , to provide users with functions such as recording memos and even drawing. For example, when taking class or meeting minutes, you don't need to use a traditional notebook, as long as you carry an electronic notebook with text input function, you can use it to record the content that needs to be recorded. [0003] Currently common electronic notebooks with a handwriting input function mostly save the text input by the user's...
