Shape Registration by Optimally Coding Shapes

IEEE Transactions on Information Technology in Biomedicine, 2008
This 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).

Shape optimization with p adaptivity

AIAA Journal, 1994
A 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.

Three‐dimensional shape optimization

International Journal for Numerical Methods in Engineering, 1982
AbstractOptimal structural desingn generally deals with frame or shell structures where the optimization is limited to resizing of structural members to obtain optimum cross‐sections or thicknesses. Shape optimization solves another class of problems involving continuous structural components where the optimum shape (the shape of the boundaries and the

Optimal shape detection

Proceedings 2000 International Conference on Image Processing (Cat. No.00CH37101), 2002
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.

PDE Constrained Shape Optimization as Optimization on Shape Manifolds

2015
The 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.
