Unmanned aerial vehicles (UAVs) have gained significant attention in recent years. Low-
cost platforms using inexpensive sensor payloads have been shown to provide satisfactory …

Unmanned aerial vehicles (UAVs) have gained special attention in recent years, among
others in monitoring and inspection applications. In this paper, a less explored application …

Visual tracking for augmented reality tours is still challenging for cultural heritage sites
because of the great variation of tracking targets and environments on such sites. Even at …

We describe a probabilistic framework for detecting and tracking motion boundaries. It builds
on previous work [4] that used a particle filter to compute a posterior distribution over …

Feature detection for Unmanned Aircraft Systems (UAS) sense and avoid scenarios is a
crucial preliminary step for target detection. Its importance culminates when distant (pixel …

By sharing processor resources among threads at a very fine granularity, a simultaneous
multithreading processor (SMT) renders thread-level parallelism (TLP) and instruction-level …

Using silhouettes in uncontrolled environments typically requires handling occlusions as
well as changing or cluttered backgrounds, which limits the applicability of most silhouette …

Model-based 3D object tracking is fast and robust using 3D edges. However, traditional
edge-based approaches have difficulty handling occluding contours of curved surfaces …

Many potential applications of computer vision require a 3D tracking system which can cope
with very unpredictable, rapid motions of the camera while operating at frame rate. This …

We present techniques for rendering implicit surfaces in different pen-and-ink styles. The
implicit models are rendered using point-based primitives to depict shape and tone using …
