Current techniques of water wave visualisation such as shadowgraphy and stereophotography are widely used but are deficient in many aspects. Refraction based visualisation observes the bending of light as it traverses across a water wave -air interface. This work describes the continued development of techniques to measure the surface height of a liquid free surface. The method utilizes refract...

Verfahren erzielt wird. Inspection of Specular Surfaces with Inverse Patterns The application of inverse patterns to fast and robust mirror surface evaluation is shown. In a well controlled environment, one observes via the mirror surface a screen onto which a well-defined pattern is displayed. Evaluation of the deflected pattern is used to determine surface defects of the object under test. In...

We propose a novel formulation to express the attachment of a polygonal surface to a skeleton using purely linear terms. This enables to simultaneously adapt the pose and shape of an articulated model in an efficient way. Our work is motivated by the difficulty to constrain a mesh when adapting it to multi-view silhouette images. However, such an adaption is essential when capturing the detaile...

This paper describes a technique to represent relevant information of tree-like structures in a compact way. The technique is general. In the application described here, the images are obtained with contrast-enhanced magnetic resonance angiography (MRA). After segmentation, the vessels are reduced to fully reversible surface skeletons. Thereafter, a novel approach to curve skeletonization based...

This work is a natural continuation of our previous work [YZ]. In this paper, we give a complete classification of toric surface codes of dimension equal to 6, except a special pair, C P (4) 6 and C P (5) 6 over F8. Also, we give an example, C P (5) 6 and C P (6) 6 over F7, to illustrate that two monomially equivalent toric codes can be constructed from two lattice non-equivalent polygons.

In many high-speed automated equipment, such as placement machines in surface mount technology lines, the most important thing is to move certain device to specific positions quickly. The trajectory is not critical. These machines utilize slew motions. The process of such machines can be divided into a set of sequential tasks moving between programmed points. In order to operate the machines ef...
