Video vehicle tracking based on modified GM(1,1) model

A scheme is put forward of using GM(1,1) model to perform vehicle tracking with video. In view of the problem of traditional GM(1,1) model having good effect in short term, but having a large error in long-term tracking, the deviation of the predictive value from true value is taken as influencing factor, and GM(1,1) model is modified. The predicted value with improved GM(1,1) model is closer to truth one, and hence the long-term tracking effects can be assured. Finally vehicle tracking test verifies the effectiveness of improved alroithm, reducing the deviation of predicted value from the true one.
