We present a new approach for simplifying polygonal objects. Our method is general in that it works on models that contain both non-manifold geometry and surface attributes. It is...
We show that an affine-invariant code C of length pm is not permutation equivalent to a cyclic code except in the obvious cases: m = 1 or C is either {0}, the repetition code or it...
Sequence data is ubiquitous and finding frequent sequences in a large database is one of the most common problems when analyzing sequence data. Unfortunately many sources of seque...
Motion analysis is an important component of surveillance, video annotation and many other applications. Current work focuses on the tracking of moving entities, the representatio...

We address the problem of complementing higher-order patterns without repetitions of free variables. Differently from the first-order case, the complement of a pattern cannot, in ...
