Two Optimization Methods for Raytracing Two Optimization Methods for Raytracing

Raytracing is a method to produce photo-realistic pictures. For each pixel of an image one ray is shot to nd the object, which determines the color of the pixel. Rays are also used to simulate shadows and reeections. Previously bounding volume hierarchies have been used to speed raytracing. A new method to speed the traversal of a bounding volume hierarchy is presented. Optimisation methods to ...

Projection methods in conic optimization

There exist efficient algorithms to project a point onto the intersection of a convex cone and an affine subspace. Those conic projections are in turn the work-horse of a range of algorithms in conic optimization, having a variety of applications in science, finance and engineering. This chapter reviews some of these algorithms, emphasizing the so-called regularization algorithms for linear con...

Objective-derivative-free methods for constrained optimization

We propose feasible descent methods for constrained minimization that do not make explicit use of objective derivative information. The methods at each iteration sample the objective function value along a finite set of feasible search arcs and decrease the sampling stepsize if an improved objective function value is not sampled. The search arcs are obtained by projecting search direction rays ...

Constrained optimization methods for direct blind equalization

Constrained optimization techniques are studied in this paper for direct design of linear multichannel equalizers. Novel blind algorithms are derived by minimizing the equalizer’s output variance subject to appropriate constraints. The constraints are chosen to guarantee no desired signal cancellation, and their parameters are jointly optimized to maximize the signal component at the output. Th...
