Optimal image alignment with random projections of manifolds: algorithm and geometric analysis

Pascal Frossard, Daniel Kressner, Effrosyni Kokiopoulou

This paper addresses the problem of image alignment based on random measurements. Image alignment consists of estimating the relative transformation between a query image and a reference image. We consider the specific problem where the query image is prov ...

Robust gain-scheduled blending control of raw-mix quality in cement industries

Alireza Karimi, Michael Amrhein, Vinicius De Oliveira

This paper addresses the control of the blending process in cement industries. This process can be modeled by a nonlinear multivariable system with large parametric uncertainty. Using a specific transformation, a linear parameter varying (LPV) model with s ...

GPU-accelerated Convex Multi-phase Image Segmentation

Jean-Philippe Thiran, Xavier Bresson, Subrahmanyam Venkata Ravi Mohana Sai Gorthi, Hadrien Copponnex, Arnaud Le Carvennec

Image segmentation is a key area of research in computer vision. Recent advances facilitated reformulation of the non-convex multi-phase segmentation problem as a convex optimization problem (see for example [2, 4, 9, 10, 13, 16]). Recently, [3] proposed a ...

Fixed-order H-infinity controller design for systems with ellipsoidal parametric uncertainty

Alireza Karimi, Arash Sadeghzadeh

In this paper, fixed-order robust H-infinity controller design for systems with ellipsoidal parametric uncertainty based on parameter dependent Lyapunov functions is studied. Using the concept of Strictly Positive Realness (SPRness) of transfer functions, ...

Welfare-Maximizing Correlated Equilibria with an Application to Wireless Communication

Daniel Kuhn

The set of correlated equilibria is convex and contains all Nash equilibria as special cases. Thus, the social welfare-maximizing correlated equilibrium is amenable to convex analysis and offers social welfare that is at least as good as the games best pe ...

Dynamically deformable micromirror array for defined laser beam shaping and homogenizing

Nico de Rooij, Roland Andreas Bitterli, Jonathan Masson, Wilfried Noell

We present a dynamic laser beam shaper than can generate smooth flat top and gaussian intensity profiles. It consists of a 100% fill factor membrane, supported by beams or posts, that deforms in a shape similar to a concave linear or 2D microlens array. Th ...

Chemical Vapor Deposition Kinetics and Localized Growth Regimes in Combinatorial Experiments

Patrik Willi Hoffmann, Ali Dabirian, Yury Kuzminykh, Estelle Wagner, Giacomo Benvenuti

Laser-assisted deposition: The discovery of chemical vapor deposition (CVD) conditions under which the growth rate is a decreasing function of the precursor flux has the potential to boost the resolution of laser-assisted CVD processes whereas flux- and de ...

A comprehensive error rate for multiple testing

Jean-Philippe Thiran, Stephan Morgenthaler, Djalel Eddine Meskaldji

In multiple testing, a variety of control metrics have been introduced such as the family-wise error rate (FWER), the False Discovery Rate (FDR), False Exceedence Rate (FER), etc. We found a way to embed these metrics into a continuous family of control me ...

Continuity Properties of Law-Invariant (Quasi-)Convex Risk Functions on L∞

Gregor Svindland

We study continuity properties of law-invariant (quasi-)convex functions f : L1(Ω,F, P) to ( ∞,∞] over a non-atomic probability space (Ω,F, P) .This is a supplementary note to [12] ...
