Video content detection method and video content detection system based on self-adaption sampling

The invention discloses a video content detection method and a video content detection system based on self-adaption sampling. The video content detection method includes: establishing a training graph set, training according to the training graph set to obtain an image classifier, and subjecting a to-be-detected video to decoding to generate an image sequence; based on the self-adaption sampling method, utilizing the image classifier to perform sampling detection upon the generated image sequence, and according to a result of the sampling detection of the image sequence, judging whether the to-be-detected video is an objectionable video or not. Through the technical scheme and adoption of the dynamic self-adaption sampling method, when video content is detected, good balance is achieved in detection accuracy and detection efficiency, the detection accuracy is guaranteed, number of sampling frames is decreased, the detection efficiency is improved, and beneficial effect of rapid detection can be achieved.
