Embodiment Construction

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0030] Before explaining the embodiment of the present application in detail, the application scenario of the embodiment of the present application will be described first.

[0031] The embodiment of the present application is applied to the application scene of correcting the text image taken in the natural scene. Due to the diversity and uncertainty of the natural scene, the character recognition in the text image taken in the natural scene is difficult to be scanned by the scanner. character recognition in text images. For example, due to the randomness of shooting, the text in the text image has a certain oblique angle; there are complex textures and noises near the text area, etc. These interferences will increa...

Abstract

The embodiments of the application disclose a text image correction method and device, a storage medium and equipment, and belong to the technical field of image processing. The method comprises the following steps of: acquiring a text image to be corrected, wherein the text image contains a text; performing binarization processing on the text image to obtain a binarized region; filtering the binarized region corresponding to a non-text region in the text image through a character classification model, and generating a binarized image according to the binarized region obtained after filtering,wherein the binarized region obtained after filtering is a binarized region corresponding to the text region in the text image; projecting the binarized image to obtain an angle of inclination of thetext; and correcting the text image according to the angle of inclination. The text image correction method provided by the embodiment of the application can improve the accuracy rate of correction of the text image.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular to a text image correction method, device, storage medium and equipment. Background technique [0002] For text images captured in natural scenes, due to human factors and limitations of terminals, the text in the captured text images inevitably has a certain degree of inclination. Therefore, it is necessary to perform tilt correction on the text image first, and then perform OCR (Optical Character Recognition, Optical Character Recognition) recognition on the corrected text image. [0003] When correcting the text image, the terminal first performs binarization processing on the text image to obtain a binarized image; extracts each straight line in the binarized image through the Hough transform algorithm; based on the same line of text on a straight line The characteristic is to determine a straight line where an optimal text line is locat...
