Problems solved by technology

[0005] In view of this, the main purpose of the present invention is to solve the problem that the recognition rate of the prior art is low, and the pornographic degree of the image cannot be measured. Therefore, the present invention provides a pornographic image evaluation method, which can evaluate the pornographic degree of the input image Evaluate and output the evaluation results

Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0019] Execution environment of the present invention is formed by a computer realizing following three module groups:

[0020] 1. Skin color extraction module. The main function of this module is to perform skin color segmentation on the input image to obtain the skin color area.

[0021] 2. The feature extraction module. The main function of this module is to extract the overall feature of the image, the feature of the local part of the human body and the shape feature of the human torso from the input image, and a total of 31-dimensional features constitute a feature vector.

[0022] 3. Model training and evaluation module. The main function of this module is to extract features from a large number of manually marked i...

Abstract

The invention discloses a pornographic image evaluating method. The method comprises the following steps of: dividing the complexion of an image; extracting 31-dimensional characteristics, namely the integral characteristics of the image, the local part characteristics of a human body and human body shape characteristics, to form characteristic vectors; and training an evaluation model, evaluating the pornographic degree of an input image, and outputting an evaluation result. By the method, whether the input image is a pornographic image or not can be judged, the pornographic degree of the image can be evaluated, 0 to 100 percent of evaluation results can be output, and a larger numerical value means the higher pornographic degree of the image, so that pornographic images is convenient to filter in a classified mode.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a pornographic image evaluation method. Background technique [0002] At present, special actions to jointly rectify obscene, pornographic and vulgar information on the Internet and mobile phone media are being carried out nationwide and even around the world. Due to the poor self-control ability of teenagers, nearly 80% of juvenile delinquents have been tempted by bad information on the Internet. In order to help young netizens avoid the erosion of pornographic information and reduce their chances of committing crimes, it is particularly necessary to effectively evaluate and filter the pornographic level of images, and technically block these harmful information before teenagers get them. [0003] Most of the existing technical schemes use simple features such as skin color ratio, and fail to comprehensively consider the overall features of the image, the features...
