The minimal disturbance invariant set: Outer approximations via its partial sums
This paper is concerned with outer approximations of the minimal disturbance invariant set (MDIS) of a discrete-time linear system with an additive set-bounded disturbance. The k-...

On sparse representations of linear operators and the approximation of matrix products
—Thus far, sparse representations have been exploited largely in the context of robustly estimating functions in a noisy environment from a few measurements. In this context, the...

Distance-Preserving Approximations of Polygonal Paths
Given a polygonal path P with vertices p1, p2, . . . , pn and a real number t ≥ 1, a path Q = (pi1 , pi2 , . . . , pik ) is a t-distance-preserving approximation of P if 1 = i1 &...

Generic Multi-scale Segmentation and Curve Approximation Method
Abstract. We propose a new complete method to extract significant description(s) of planar curves according to constant curvature segments. This method is based (i) on a multi-sca...
