[0075] The present invention provides a multi-factor suspicious person identification method based on video feature learning, learning video features, and judging suspicious persons according to multiple factors. Foreground information, and locate the area where key parts are located; then perform dynamic and static feature extraction on the preprocessing results: for static surveillance videos, extract local features such as head posture and hand posture, and overall features such as abnormal walking and abnormal clothing; for dynamic Monitoring features, mainly extracting the repeatability of paths, the probability of suspicious persons appearing in densely populated points, and the average stay time of landmarks in the monitoring environment; according to the evaluation criteria combined with the idea of trusted computing, the identity credibility index of suspicious persons is calculated; finally, according to the corresponding threshold, dynamically screen suspicious per...
