Simulate GPS tracking Object 2D and smooth its obits by Kalman filter.

Lee滤波，用于对图像进行去斑点噪声，以及对图像进行平滑处理-Lee filter, the image smooth processing

On the basis of Kalman filter, the raw data signal can be converted to a more smooth signal.

In the existing bilateral filtering algorithm, the domain parameters and range parameters need to be predefined. Parameters of a bilateral filter are fixed and cannot guarantee to be optimal. A new adaptive bilateral filtering (ABF) is proposed i
