Embodiment Construction

[0053] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0054] figure 1 It is a flowchart of an image processing method shown according to an exemplary embodiment. Such as figure 1 As shown, the image processing method is used in a terminal device such as a mobile phone, a tablet computer or a personal computer, and includes the following steps S101-S103:

[0055] In step S101, a classification algorithm is used to perform classification...

Abstract

The invention discloses a picture processing method and device to improve the definition of character pictures and enable a user to recognize the content in the character pictures conveniently. The method comprises the steps that classifying training is carried out through pictures in a preset training set via a classification algorithm to obtain a judging model used for distinguishing the character pictures and the non-character pictures, wherein the preset training set comprises the character pictures and the non-character pictures; whether a picture to be processed is a character picture or not is judged through the judging model; if yes, image enhancing is carried out on the picture to be processed through an image normalization algorithm. By means of the picture processing method and device, the definition degree of the characters in the character pictures can be increased, and the user can recognize the character content in the character pictures easily; compared with the method that enhancement processing is carried out on all pictures to be processed, the picture processing method and device have the advantages that by means of the technical scheme, enhancement processing is carried out only on the character pictures, the image processing burden is relieved, and resources in the device are saved.

Description

technical field [0001] The present disclosure relates to the field of image technology, and in particular to an image processing method and device. Background technique [0002] With the development of smart terminal technology, users can use the camera in the terminal to take pictures of text, such as taking pictures of announcements and classroom PPT (Microsoft presentation software), and obtain pictures containing text content. The pictures containing text content are called for text images. In related technologies, the text and picture can be stored in a designated folder, and the text and picture can also be inserted in the application as a sticky note. For example, inserting a picture of text as a sticky note in a notepad app or a calendar app. The defect of the related technology is that no text image is processed, and the clarity of the text image depends entirely on the quality of the original image taken, so that when the photographed text image is blurred, it is...
