Embodiment Construction

[0049] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0050] figure 1 is a schematic flowchart of a character recognition method provided by an embodiment of the present invention, see figure 1 , the method can include:

[0051] Step 101, performing a first character recognition on the target content in the target image to obtain a first recognition result.

[0052]Step 102 , performing semantic analysis on the first recognition result to identify characters whose character attributes are letters and characters whose character attributes are numbers among the characters in the first recognition result.

[0053] Step 103, marking characters whose character attributes are letters as letters, and marking characters...

Abstract

The invention discloses a character identifying method and device and relates to the technical field of image-text processing. The method includes performing semantic analysis on an obtained first identification result after performing primary character identification of target content in a target image so as to identifying characters whose character attribute is alphabet and characters whose character attribute is number in the first identification result; marking the characters whose character attribute is alphabet as alphabet and marking the characters whose character attribute is number as number; performing secondary character identification on positions of the characters with marks in the target image and obtaining a second identification result; outputting a character identification result of the target content according to the first identification result and the second identification result. Therefore, a problem of alphabet-number confusion proneness can be solved and character identification accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of graphic and text processing, in particular to a character recognition method and device. Background technique [0002] At present, OCR (Optical Character Recognition, Optical Character Recognition) is a commonly used image-based character recognition technology. This technology uses optical methods to convert text in paper documents into black-and-white The text in the image is converted into a text format for further editing and processing by word processing software. With the continuous maturity of OCR technology, its application scope is also more and more extensive. [0003] However, the existing OCR technology is easy to confuse the letters and numbers in the image when recognizing them, which affects the accuracy of character recognition. Contents of the invention [0004] The invention provides a character recognition method and device, which are used to solve the problem that letters a...
