Aiming at the difficulties on stably and timely tracking vehicle on the scenes such as volatile moving direction,varying pose and distance,illumination change,etc.,integrating autocorrelation matrix,incremental learning on IPCA and particle filter algorithm,new kind of vehicle tracking methods using appearance model is proposed. When beginning at original tracking time,the proposed method can timely learn the characteristic subspace images of vehicle,using autocorrelation matrix and eigen value decomposition. Based on IPCA incremental learning,likelihood probability density is computed on subspace mean and eigenvector,increasing computational precision on weights of particles on particle filter algorithm. The tracking results demonstrate that success tracking rate of the proposed AM-IPCA vehicle tracking method is raised to 95.1%~96.4%,compared with 82.7%~92.3% of P.Hall-IPCA and 92.1%~95.2% of D.Ross-IPCA appearance model tracking method.
