Abstract

The embodiment of the present invention relates to the technical field of image processing, and discloses a method and device for positioning image characters. The method includes: marking the text image with connected domains, obtaining at least one text connected domain, dividing at least one text connected domain into rows according to the azimuth angle, and obtaining at least one row unit, where the azimuth angle is the center point of any two text connected domains The angle between the straight line and the horizontal line; according to the interdomain distance, at least one text connected domain is divided into columns to obtain at least one column unit, and the interdomain distance is the distance between the center points of any two text connected domains; according to at least one row unit and at least one The row unit determines at least one text positioning frame, which is used to indicate the position of the text contained in the text image, and one text positioning frame corresponds to one text. Implementing the embodiment of the present invention can improve the accuracy of image text positioning.

Description

technical field

[0001] The invention relates to the technical field of image processing, in particular to a method and device for positioning image characters. Background technique

[0002] In the era of mobile Internet, people use cameras on smart devices to capture the world they see every day, resulting in a surge in image and video data, creating the era of image big data. Nowadays, people rely on image recognition, and there is an increasing demand for extracting text information from captured text images. For example, during the learning process, students often need to extract text information from captured text images to search for answers. In this process, the text image recognition task can be divided into two main stages, one is text positioning, and the other is text recognition. Among them, text positioning is to determine the position of the text in the image. The accuracy of text positioning has a profound impact on the accuracy of text recognition. Simply pu...
