Embodiment Construction
[0034] As shown in the figure, a module structure for detecting abnormal target behavior in intelligent visual surveillance includes:
[0035] Target tracking module 110: sampling the image sequence containing the moving target to generate the target motion trajectory;
[0036] Trajectory database 115: store target motion trajectory;
[0037] Preprocessing module 120: use the moving average filter to filter out the noise of the target trajectory, make it smooth, and describe the target trajectory with a spatial descriptor;
[0038] Sub-track extraction module 125: extract the sub-track set of the target motion track, and merge to form a sub-track data set;
[0039] Sub-trajectory pattern network 130: use the first self-organizing feature map network to learn the sub-trajectory data set, and generate a set of sub-trajectory distribution patterns;
[0040] Sub-track anomaly detection information generation module 135: calculate the abnormal threshold of each sub-track distribu...
