electrical steels are important alloys widely used in electrical instruments. the magnetic properties and low core loss of grain oriented silicon steels are closely related to the sharpness of goss texture ({110} ).the direction of is the softest direction for magnetism.  in this work, the microstructure and dependence of orientation density along the major texture fibers on the applied cold ro...

This thesis presents contributions to two major topics in computer graphics. The first part describes new algorithms for tile-based synthesis of blue noise point sets and solid textures; the second part describes systems for capturing, viewing, and manipulating outdoor photographs. Well distributed point sets play an important role in computer graphics, as well as many other fields, since they ...

In the questfor visual realism in computer graphics, surface textures are generated for objects based on a texture image or some procedural model. Similar approaches can be used to make objects feel more realistic with a haptic intelface. By using an object oriented approach, a sofhvare structure was created to allow the inclusion of various texture rendering algorithms for a 3 DOF haptic devic...

There exist many computer graphics techniques which could achieve high quality tree generation. However, only a few works focus on realistic modeling of tree bark. Difficulties lie in the complex appearance of the bark surfaces which are largely determined by their mesostructures. Unlike traditional physical based methods, in this paper, we present an appearance-based method to model tree bark ...

Thanks is due to Thomas Vetter, who kindly provided his implementation of the algorithm determining correspondence between the faces. We also thank Dieter Grass, Renate Nowotny and Michael Pollirer for valuable assistance in the pigeon laboratory. Abstract. Pigeons are known to be able to categorize a wide variety of visual stimulus classes. However, it remains unclear which are the characteris...

We investigate whether observers take into account their visual uncertainty in an optimal manner in a perceptual estimation task with explicit rewards and penalties for performance. Observers judged the mean orientation of a briefly presented texture consisting of a collection of line segments. The mean and, in some experiments, the variance of the distribution of line orientations changed from...

In this work, we investigate the visual appearance of real-world surfaces and the dependence of appearance on scale, viewing direction and illumination direction. At ne scale, surface variations cause local intensity variation or image texture. The appearance of this texture depends on both illumination and viewing direction and can be characterized by the BTF (bidirectional texture function). ...
