Abstract


Technological advances make the network along with the rapid development of the Internet is like a double-edged sword , people are still rejoicing in the power of the web when many immoral people also took the opportunity to channeling in they upload many obscene , pornographic pictures serious pollution of cyberspace . Many researchers blocked pornographic websites , text message with the word sensitive filtering and other methods to control the spread of pornography on the network , but the control of these pornographic images are not very effective , so sensitive image content-based filtering technology came into being. In this paper, based on the specific content of the sensitive image filtering technology , the contents are as follows . Sensitive image filtering module skin detection module, the the texture detection module , feature extraction module and classification module . Skin detection module , through experiments compare our proposed method of combining color space models and statistical histogram model for skin detection , experimental results show that relative to traditional color space model , Gaussian mixture model , histogram model than the detection rate increased to 2.32 ( frames / sec ) . Texture detection module , five common texture algorithm , on this basis, an edge detection method based on the Particle Swarm fuzzy clustering algorithm and the Gabor function combination skin texture detection achieved good experimental results . This can be seen by comparison with the DCT transform method on the accurate detection rate of 16% , the false detection rate has dropped by 22% , the experimental results are very satisfactory . This selection of the decision tree classifier selection as the classifier . The experimental results show that the filtering of sensitive images have a significant effect, be able to distinguish the normal image and the normal image .
