a compound image matching model and a recognition method were developed

namely classifying vehicles firstly by utilizing Harris corner

then classifying vehicles detailedly by using SIFT feature.Compared with the one used SIFT feature only

the method shortens the time of disposal by 2/3 under guaranteeing the accuracy to be kept essentially constant...
