Image-based object modeling enables us to compose photorealistic images of modeled objects for various rendering conditions (viewpoints/light directions, etc.) However, it is very challenging to acquire a huge number of object images for all combinations of capturing parameters and to then handle the resulting huge data sets for the model. In this paper, we present a novel modeling method for a...

Texture analysis and synthesis has been studied extensively by many vision and graphics researchers. A very useful concept in texture analysis is texton or the basic element of a texture image. However, it remains unclear how to define a texton despite the fact that Julesz proposed the term ”texton” more than twenty years ago. In this talk, I will propose a two-level statistical model with text...

We present a novel technique for texture mapping on arbitrary surfaces with minimal distortions, by preserving the local and global structure of the texture. The recent introduction of the fast marching method on triangulated surfaces [9], made it possible to compute geodesic distances in O(~ n lg ~ n) where ~ n is the number of triangles that represent the surface. We use this method to design...

This paper uses theory, simulation, and laboratory experiment, to show that directional illumination, used during the image acquisition process, acts as a directional filter of three dimensional texture. It is shown that the directional characteristics of image texture are not intrinsic to the physical texture being imaged, as they are affected by the direction of the illumination. This result ...

The goal of this research was to develop algorithms for synthesis of specific textures in multi-spectral images. In plain terms, we started with an image of grass texture (64 by 64 pixels), in fact, 42 images of the same area in different spectral wavelengths (including the visible spectrum) (see Figure 1 for an example). The goal was to create a similar multispectral image, which would look li...

Volume rendering with texture mapping hardware is a fast volume rendering method available on high-end workstations. However, limited texture memory often prevents the method from being used to render large volume data efficiently. In this paper, we propose a new approach to fast rendering of large volume data with texture mapping hardware. Based on a new volume-loading pipeline, the volume dat...

The construction and long-term operation stage of the rock slope with argillaceous interlayer will be subjected to intermittent dynamic loads, such as blasting earthquake. For in slope, its rheological properties are not only related initial stress state caused by gravity overlying mass but also affected loads. In order investigate intercalation under combination static shear tests argillic int...
