Exploring the use of glossy light volumes for interactive global illumination
From the literature, it is known that backward polygon beam tracing and other light volume methods are well suited to gather path coherency from specular scattering surfaces. This...

Coding Partitions: Regularity, Maximality and Global Ambiguity
The canonical coding partition of a set of words is the finest partition such that the words contained in at least two factorizations of a same sequence belong to a same class. In...

Globally Optimal Grouping for Symmetric Closed Boundaries by Combining Boundary and Region Information
Many natural and man-made structures have a boundary that shows a certain level of bilateral symmetry, a property that plays an important role in both human and computer vision. In...

Nonnegative 3-way tensor factorization via conjugate gradient with globally optimal stepsize
This paper deals with the minimal polyadic decomposition (also known as canonical decomposition or Parafac) of a 3way array, assuming each entry is positive. In this case, the low...

Using Local Trajectory Optimizers to Speed Up Global Optimization in Dynamic Programming
Dynamic programming provides a methodology to develop planners and controllers for nonlinear systems. However, general dynamic programming is computationally intractable. We have ...
