High-precision maneuvering target contour tracking method based on Kalman filtering algorithm

This paper presents a high-precision maneuvering target contour tracking method based on Kalman filtering algorithm for video, against to the requirement to express the target contour accurately in engineering, and the fact that presently most of target tracking methods in video are not precise, target is easy to lose. By compensating the priori state error in update process of Kalman filtering algorithm, the method in this paper can track the target contour which occasionally moves sharply, especially it is suitable for the condition that target outline is clear against background. This method provides an approach to get target contour as well as internal information precisely, and has practical value in engineering. By the analysis of experiment, when severe maneuvering of the target happens or in the environment where there is background contour interference, the method can still track the target contour accurately, in addition it is easy to implement and has good real-time performance.
