Problems solved by technology

It can be seen from the above that the misjudgment rate of the existing image filtering technology is relatively high. After filtering, there are still a large number of images that need to be judged manually, resulting in a waste of human resources, and a large number of mixed images also affect the accuracy of manual judgment.

Embodiment 1

[0067] In order to solve the above technical problems, an embodiment of the present invention firstly provides a picture classification model, Figure 1-2 It is a schematic diagram of the formation process of an image classification model in the embodiment of the present invention, as Figure 1-2 As shown, the specific process includes the following steps:

[0068] Step S101, the preliminary filtered pictures 10 are screened to form a primary training database 11;

[0069] Here, the pre-filtered picture 10 is used as the input of the system. Of course, the input of the system may also be a picture that has not been pre-filtered. Here, the pre-filtered picture 10 is taken as an example. In the specific implementation process, the pre-filtered pictures can be stored in a separate picture library, which includes a certain proportion of illegal pictures. If the conventional processing method is used, there will be a large misjudgment rate.

[0070] Step S102, classify the pictur...

Embodiment 2

[0091] Based on the foregoing first embodiment, the embodiment of the present invention provides an image processing method, which is applied to electronic equipment, and the electronic equipment refers to equipment with computing capabilities, such as personal computers, servers, industrial control computers, notebook computers Wait. The functions realized by the image processing method provided by the embodiment of the present invention can be realized by calling the program code by the processor in the electronic device.

Abstract

The invention discloses an image processing method. The method comprises the following steps of classifying a to-be-processed image by utilizing a preset image classification model, so as to obtain a classification result, wherein the image classification model is obtained through training images in a classified image library by utilizing a support vector machine method, and the classification result indicates the classified image library, to which the to-be-processed image belongs; obtaining a first image which serves as a contrast image from the classified image library, to which the to-be-processed image belongs, wherein the first image is an image in the classified image library, to which the to-be-processed image belongs; calculating a hash distance between the to-be-processed image and the contrast image; and removing or retaining the to-be-processed image according to the hash distance. The invention furthermore discloses an image processing device.

Description

technical field [0001] The present invention relates to image processing technology, in particular to an image processing method and device. Background technique [0002] With the rapid development of Internet business and the rapid popularization of fourth-generation (4G) communication technology, people obtain more and more information from the Internet, and the amount of dissemination of pictures is also increasing. At the same time, the dissemination of various illegal pictures also seriously interferes with the normal life and physical and mental health of people, especially minors, affects the order of social operation, causes adverse social impact, brings negative energy, and endangers the operators' reputation. Corporate image. To this end, we need to take measures to classify, identify, and filter illegal pictures to create a greener and healthier Internet environment. [0003] Existing image filtering technologies mainly identify pornographic images directly. Fo...
