Rapid detection method for pornographic videos based on Gaussian distribution

The invention provides a rapid detection method for pornographic videos based on Gaussian distribution. The detection method includes building a Gaussian model for color histograms of hue, saturation and value (HSV) color space of general picture samples and pornographic picture samples; and extracting key frames in videos and judging the key frames in videos by utilizing the built Gaussian model. If a certain number of key frames are judged as porn in a video, the video can be judged as a pornographic video. According to the rapid detection method for the pornographic videos based on the Gaussian distribution, the Gaussian distribution model is only needed to be built for the color histogram, no complex training process is needed, no detection for each key of the videos is required, therefore the detection is fast, and the accuracy rate is high.
