Negatively charged nitrogen vacancy centers (NV−) in diamond serve as highly sensitive, optically readable sensors for magnetic fields. Improved sensing approaches rely on NV− embedded nanopillar waveguides, which enable scanning probe imaging and use multi-color laser schemes efficient spin readout. In this work, we investigate the free-beam coupling of most relevant wavelengths to nanopillars...

With many visual speech animation techniques now available, there is a clear need for systematic perceptual evaluation schemes. We describe here our scheme and its application to a new video-realistic (potentially indistinguishable from real recorded video) visual-speech animation system, called Mary 101. Two types of experiments were performed: a) distinguishing visually between real and synth...

A number of labeling schemes have been designed to facilitate the query of XML, based on which the ancestor-descendant relationship between any two nodes can be determined quickly. Another important feature of XML is that the elements in XML are intrinsically ordered. However the label update cost is high based on the present labeling schemes. They have to re-label the existing nodes or re-calc...

We propose an enhanced image reconstruction method for spotlight-mode synthetic aperture radar (SAR). Our approach involves extension of feature preserving regularization techniques developed in other applications to the complex-valued SAR imaging problem. Compared to conventional image formation schemes, our approach offers increased resolvability of point-scatterers, enhancement of object sha...

Over the past years the Internet has evolved to the most important medium of communication for science and teaching. Besides the man-to-man communication and the role of the Internet as a publication medium, the Internet provides access to huge amounts of scientific data and algorithms. The main focus of scientific visualization is, to provide people insights into the main information contained...
