Embodiment 1

[0042] In order to solve the technical problem in the prior art that the implementation time complexity is relatively high and real-time processing cannot be performed at the terminal, an embodiment of the present disclosure provides an image processing method. Such as figure 1 As shown, the image processing method mainly includes the following steps S11 to S13.

[0043] Step S11: Acquire the first image to be processed, and identify the text area included in the first image.

[0044] Wherein, the first image is an image containing text content (for example, lyrics, lines), that is, a text image.

[0045] Specifically, it may be a video image acquired in real time, for example, a live video in a short video application, or a video image or picture pre-stored in the terminal. Wherein, the terminal may be a mobile terminal, such as a smart phone or a tablet computer, or may be a fixed terminal, such as a desktop computer.

[0046] Step S12: Process the text area into at least...

Embodiment 2

[0064] In order to solve the technical problem of high time complexity in the prior art and the inability to perform real-time processing at the terminal, an embodiment of the present disclosure provides an image processing method. This embodiment is a specific embodiment, which is used to implement the technical The program is explained. Such as Figure 2a As shown, the image processing method mainly includes the following steps S21 to S27.

[0065] Step S21: Acquiring the first image to be processed, and identifying the text area included in the first image.

[0066] Specifically, such as Figure 2b Shown is an example of the first image, in which the text areas are arranged in rows.

[0067] Step S22: reducing the first image by a preset multiple to obtain a second image.

[0068] Such as Figure 2c Shown is an example of the second image obtained.

[0069] The purpose of this step reduction is to reduce the size of the image to speed up the algorithm.

[0070] Step ...

Embodiment 3

[0085] In order to solve the technical problem in the prior art that the implementation time complexity is relatively high and real-time processing cannot be performed at the terminal, an embodiment of the present disclosure provides an image processing device. The device can execute the steps in the image processing method embodiment described in the first embodiment above. Such as image 3 As shown, the device mainly includes: a character recognition module 31, a line segment processing module 32 and a word processing module 33; wherein,

[0086] The text recognition module 31 is used to obtain the first image to be processed, and identify the text area contained in the first image;

[0087] The line segment processing module 32 is used to process the text area into at least one continuous line segment; wherein, a line or a column of text corresponds to a line segment respectively;

[0088] The text processing module 33 is configured to process the text area according to t...

Abstract

The invention discloses an image processing method, device, electronic equipment and computer-readable storage medium. The method includes: acquiring the first image to be processed, and identifying the text area contained in the first image; processing the text area into at least one continuous line segment; wherein, a line or a column of text corresponds to a line segment respectively; according to The line segment processes the text area to obtain a target image. In the embodiment of the present disclosure, the text area in the first image to be processed is processed into at least one continuous line segment; wherein, a line or a column of text corresponds to a line segment, and the text area is processed according to the line segment to obtain the target image , which can reduce the computational complexity and enable real-time processing at the terminal.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to an image processing method, device, and computer-readable storage medium. Background technique [0002] With the development of smart terminal technology, users can use the camera in the terminal to take photos of texts, such as lyrics, scripts, etc., to obtain pictures containing text content. The pictures containing text content are called text pictures. [0003] When the text picture is displayed on the terminal later, in some cases, it is necessary to mark the text in the text picture, for example, to line the text by line, then it is necessary to identify the start position and end position of each line of text. [0004] In the prior art, additional text information or iterative search is often required for position recognition of text in text pictures. This implementation has high time complexity and cannot be processed in real time at the terminal. ...
