比较特殊的unsented 卡尔曼滤波器 只采用了2n个sigma points而不是2n+1 减少了运算时间-2N sigma point kalman filter

sigma点卡尔曼滤波在跟踪中的应用，能够实现较好的跟踪效果-sigma point Kalman filter in tracking application, can achieve better tracking

包括kf，ekf，pf，upf可以自己定制模型参数，完成滤波-ReBEL currently contains most of the following functional units which can be used for state-, parameter- and joint-estimation: Kalman filter Extended Kalman filter Sigma-Point Kalman filters (SPKF) Unscented

国外的迭代非线性滤波，比UKF更为实用，以往对大家有帮助-the The Iterated Sigma Point Kalman Filter，is more efficient than UKF
