Shape Registration by Optimally Coding Shapes
IEEE Transactions on Information Technology in Biomedicine, 2008This paper formulates shape registration as an optimal coding problem. It employs a set of landmarks to establish the correspondence between shapes, and assumes that the best correspondence can be achieved when the polygons formed by the landmarks optimally code all the shape contours, i.e., obtain their minimum description length (MDL).

We present a new approach for accurate detection of two-dimensional shapes. We first derive an optimal smoothing filter, which minimizes both the noise power and the mean squared error between the input and the filter output. This operator is found to be a derivative of the double exponential (DODE) function.

Shape optimization with p adaptivity
AIAA Journal, 1994A methodology is developed to integrate \(p\)-adaptive analysis with shape optimization for general velocity fields. The key contributions lie in an easily implementable shape update strategy and in an adaptive scheme to locally increase the polynomial order based on error indicators.

PDE Constrained Shape Optimization as Optimization on Shape Manifolds
2015The novel Riemannian view on shape optimization introduced in [14] is extended to a Lagrange–Newton as well as a quasi–Newton approach for PDE constrained shape optimization problems.

Access to the shape by its exterior is solved using convex hull. Many algorithms have been proposed in that way. This contribution addresses the open problem of the access of the shape by its interior also called convex skull. More precisely, we present approaches in discrete case.

This paper is concerned with the optimal shape of cables subject to external loads only. Design-dependent loads (e.g. selfweight) are assumed to be negligibly small. Consequently, the cable axis is given by the funicular for the prescribed loads.

Optimally Directed Shape Generation by Shape Annealing
Environment and Planning B: Planning and Design, 1993The new design technique of shape annealing is introduced. Shape annealing is a variation of the simulated annealing stochastic optimization technique. It produces optimally directed shapes within the language specified by a shape grammar.

Optimality Conditions for Simultaneous Topology and Shape Optimization
SIAM Journal on Control and Optimization, 2003Summary: New optimality conditions are derived for a class of shape optimization problems. The conditions are established on the boundary by an application of the boundary variations technique and in the interior of an optimal domain by exploiting the topological derivative method.
