Abstract In ice and snow weather, the surface texture characteristics of asphalt pavement change, which will significantly affect skid resistance performance pavement. this study, five mixture types AC-5, AC-13, AC-16, SMA-13, SMA-16 were prepared under three conditions original state, snow. paper, a 2D-wavelet transform approach is proposed to characterize micro macro The Normalized Energy (NE...

Schizophrenia patients are less susceptible to depth inversion illusions (DIIs) in which concave faces appear as convex, but what stimulus attributes generate this effect and how does it vary with clinical state? To address these issues, we had 30 schizophrenia patients and 25 well-matched healthy controls make convexity judgments on physically concave faces and scenes. Patients were selectivel...

We present a method for overlaying a texture onto a non-rigid surface using a commodity depth camera. The depth cameras are able to capture 3-D data of a surface in real-time, and have several advantages compared with methods using only standard color cameras. However, it is not easy to register a 3-D deformable mesh to a point cloud of the non-rigid surface while keeping its geometrical topolo...

In the field of Abrasive Water Jet (AWJ) machining, the current focus is on the fabrication of complex threedimensional features. The current work is aimed at using this strategy to manufacture micro-tools for machining arrays of square holes using Electric Discharge Machining (EDM). Based on selected parameters of AWJ process(step over, traverse speed, path strategy),micro tools were fabricate...

Transparency can be a useful device for depicting multiple overlapping surfaces in a single image. The challenge is to render the transparent surfaces in such a way that their three-dimensional shape can be readily understood and their depth distance from underlying structures clearly perceived. This paper describes our investigations into the use of sparsely-distributed discrete, opaque textur...

The evaluation of texture in digital remote sensing, is traditionally accomplished by applying statistical, rather than structural models. This approach is partially due to the difficulty in determining structural placement rules for natural scenes, and to early psychophysical texture theories that demonstrated humans were sensitive to second-order statistics. A literature review indicates that...
