A video surveillance system is disclosed. The system includes a model database storing a plurality of models and a vector database storing a plurality of vectors of recently observed trajectories. The system includes a model building module that builds a new motion model corresponding to the motion data of the current trajectory data structure. The system generates a current trajectory data structure having motion data and abnormality scores. The system also includes a database purging module configured to determine a subset of vectors that is most similar to the current trajectory data structure based on a measure of similarity between the subset of vectors and the current trajectory data structure. The database purging module is further configured to replace one of the motion models in the model database with the new motion model based on an amount of vectors in the subset vectors the recentness of the subset of vectors.
A surveillance system having a surveillance processing circuit that receives metadata of image data, the surveillance processing circuit comprising:
The surveillance system of 1, further comprising a dynamic model database storing a new normal motion model, and a database purging processing circuit managing the dynamic model database;
A method for processing image data in a surveillance system, comprising:
A computer program product comprising a non-transitory computer-readable medium having a computer-readable program code embodied therein, said computer-readable program code adapted to be executed by a processor to implement a surveillance method operating on image data, said method comprising:
