The class of median filters has been extended to include weighted order statistics (WOS) filters, to improve the flexibility of the filtering operation. The WOS filter weights each input within a sample window, and thus retains the original temporal order information. In this paper, we present efficient VLSI architectures for nonrecursive and recursive WOS filters based on (i) array (ii) stack ...

The task of determining the distance from one object to another is important tasks solved in robotics systems. Conventional algorithms rely on an iterative process predicting estimates, which results increased computational burden. Algorithms used robotic systems should require minimal time costs, as well be resistant presence noise. To solve these problems, paper proposes algorithm for Kalman ...
