分析并综合了联邦滤波算法，以及该算法存在的问题，提出了针对观测信息不足的情况下的算法-Analysis and synthesis of the federated filtering algorithm, as well as the problems of the algorithm is proposed for the observed absence of sufficient information the algorithm

Altitude location for UAV by using federated filter is discussed, the fourth structure is selected, because its two sub-filters involving altitude sensor and the difference Global Positioning System (d-GPS) respectively are fully isolated from

We first present the Hypothesis Selection Filter in a general setting. For a given image enhancement problem, suppose we have selected a set of image filters each of which is effective in improving the image quality for a certain type of cont
