在机器视觉中追踪时常会用到预测算法，kalman是你一定知道的。它可以用来预测各种状态，比如说位置，速度等。关于它的理论有很多很好的文献可以参考。opencv给出了kalman filter的一个实现，而且有范例，该应用是对二维坐标进行预测和平滑-In machine vision often used to track prediction algorithm, kalman is that you must know. It can be used to predict various states, such as position, speed and the like. There are many theories about its well documented reference. opencv gives a realization kalman filter, and there are examples of the application is a two-dimensional coordinate forecasting and smoothing
