Trajectory Prediction Algorithm Based on Iterative Fitting

A real-time predicting trace algorithm is proposed using the process of target tracking, the target’s position in the next frame is estimated by the iterative fitting. Making the predict position as the center, the target is searched within a certain window and the target tracking is accomplished. The target’s trajectory is obtained by fitting the target’s positions using curve. The experiments show that the algorithm reduces the matching complexity, improves the tracking speed and tracking precision.
