Problems solved by technology

In the process of recognizing the text content in the image, since the image may be a photograph or handwritten text, if the text object is not facing the camera, the text in the image may be skewed. The text object is bent, for example, the part of the book page near the binding side is easy to bend, which may cause the text in the image to be distorted, because the text in the image is skewed or distorted, resulting in low recognition accuracy for the text in the image

Abstract

Embodiments of the present application provide a text image correction method, device, and computer-readable storage medium. The text image correction method includes: detecting a target image, and determining at least two text blocks; in the at least two text blocks At least one pair of text blocks that are adjacent to each other is determined, and each pair of text blocks in the at least one pair of text blocks is merged to determine at least one text line; the at least one text line is corrected. Because the text line is determined by using the bidirectional matching relationship of the adjacent text blocks, the distortion correction of the text line is more accurate.

Description

technical field [0001] The embodiments of the present application relate to the field of image processing, and in particular, to a text image correction method, device, and computer-readable storage medium. Background technique [0002] With the development of science and technology, the recognition of text content in images has become more and more widely used in life and work. For example, in the application scenario of online teaching, students upload handwritten homework pictures or exam papers, and the computer automatically corrects them. The text content is recognized; for another example, in the scenario of automatic verification of the certificate / certificate, the text content in the image of the certificate / certificate also needs to be recognized. In the process of recognizing the text content in the image, since the image may be a photograph or handwritten text, if the text object is not facing the camera, the text in the image may be skewed. Text objects are ben...
