Embodiment Construction

[0079] In the embodiment of the present application, the target area image is processed, and the characters in the target area image are combined and divided into at least one character area according to the character position information in the target area image. The characters identified in the character area are searched in the pre-stored area database to obtain the matching value of each character area and each area in the database, and the target area image and the target area image are obtained according to the matching value. The best matching result for each set of regions in the database. The present application can accurately realize the automatic search of the target area in the text recognition.

[0080] While the present application is capable of embodiments in many different forms, certain embodiments have been shown in the drawings and will be described in detail herein, it being understood that the disclosure of such embodiments should be considered as an illus...

Abstract

An embodiment of the present application provides a method and device for searching a target area in text recognition, the method comprising: merging and / or segmenting characters in the target area image into at least one character area according to character position information; The characters identified in the character area are searched for the characters in each character area in the pre-stored area database, and the matching value of each character area and each character area in the database is obtained; according to the target area The matching value of each character region in the image and each character region in the database is used to obtain the best matching result between the target region image and each region set in the database. The embodiment of the present application can accurately realize the automatic search of the target area in text recognition.

Description

technical field [0001] The present application belongs to the technical field of image recognition, and in particular relates to a method and a device for searching a target area in text recognition. Background technique [0002] OCR (Optical Character Recognition, Optical Character Recognition) means that an electronic device (such as a scanner or a digital camera) checks characters printed on paper, determines its shape by detecting dark and bright patterns, and then uses character recognition to translate the shape into a computer The process of text; that is, for printed characters, the text in the paper document is converted into a black and white dot matrix image file by optical means, and the text in the image is converted into a text format by recognition software for further processing by word processing software Editing technology. [0003] In the application products related to OCR technology, the captured image area may contain the text area corresponding to the...
