In this paper, we introduce a new algorithm framework for motion trajectories
cluster and match. Simulation results demonstrate that extracting main features
and modified k-means cluster method approach good results on normal and
abnormal trajectories classification. Gaussian Process Regression model makes
partial trajectory match for the right class, which neglects trajectory integrity .
Its training samples got from previous classification also get ride of surrounding
constrains. But there are still some problems unthoughtful. The criterion setting
of whether target trajectory match for one class in Gaussian Process Regression
model needs more sample experiments.
