Embodiment Construction

[0065] The specific implementation process of the pornographic image recognition method proposed by the present invention is as follows: figure 1 shown, including the following steps:

[0066] 1. Create a sample image library.

[0067] Through research, a sample image database in the pornographic image recognition system is established. In order to improve the recognition accuracy, the database needs to contain as many pornographic images as possible of various key parts of nudity, and various typical normal images (animals, plants, etc.) , scenery and people's life photos).

[0068] 2. Extract features from sample images

[0069] Color is the most basic and stable feature in an image, and it is enough to fully and accurately express the content of pornographic images. If other features such as shape are added, the amount of calculation is increased, and the accuracy cannot be greatly improved due to the immaturity of shape recognition. The implementation process of color ...

Abstract

The invention relates to a pornographic image recognizing method comprising: a first step of establishing a sample image database; a second step of extracting characteristics of sample images; a third step of training the characteristics extracted from the sample images to form a pornographic image classifier; a fourth step of extracting the characteristics of an image needing to be recognized; and a fifth step of inputting the characteristics of the image needing to be recognized in the pornographic image classifier, thus obtaining a recognition result. The image characteristics employ a color histogram characteristic vector consisting of determined values, fuzzy values and intuition values together. The invention further comprises a step of optimizing the image characteristics by genetic algorithm. When in use, the method can increase the image recognition accuracy and shorten the recognition time.

Description

technical field [0001] The invention relates to a method for recognizing pornographic images, belonging to the technical field of image recognition. Background technique [0002] Human society has entered the information age, and the rapid dissemination of information has changed human work, study and lifestyle. The form of information is diversified (text, image, voice, etc.); the content of information is also diversified. While promoting the progress of human society, there is a large amount of bad information that has a very bad impact on society, such as pornographic image information, which is one of the One of the most widely disseminated and most difficult to control information. [0003] With the continuous advancement of the informatization construction of various domestic departments, in order to meet various work needs, the services provided in the network continue to increase, which provides an entry point for violations of regulations through these services, s...
