Computer models of the real world often use images of the environment to capture realistic visual complexity. Image-based modeling techniques permit the creation of geometric models with a high level of visual detail from photographs. These models are textured by resampling these images of the scene; we call this process image-based texturing. The problem with traditional image-based texturing ...

This thesis discusses methods for using the information in motion capture data to assist in the creation of life-like animations. To address the problem of developing better methods for collecting motion capture data, we focus on video motion capture. A new factorization method is presented that allows one to solve for the model of the subject’s skeleton from a series of video images. No marker...

Hemispherical reflectance and internal quantum efficiency measurements have been employed to evaluate the response of Si nanostructured surfaces formed by using random and periodic reactive ion etching techniques. Random RIE-textured surfaces have demonstrated solar weighted reflectance of= 3 ‘?XO over 3001200-nm spectral range even without the benefit of anti-reflection films. Random RIE-textu...

In this article we present a low cost 3 0 face modeling scheme that uses only an overhead projectoq a camera and a plane object. We deal with the calibration of such a system, the 3 0 face reconstruction itself; and then the texturing of the resulting 3 0 shape.

Reprojection of texture issued from cameras on a mesh estimated from multi-view reconstruction is often the last stage of the pipeline, used for rendering, visualization, or simulation of new views. Errors or imprecisions in the recovered 3D geometry are particularly noticeable at this stage. Nevertheless, it is sometimes desirable to get a visually correct rendering in spite of the inaccuracy ...

Procedural texturing is commonly used to increase visual complexity and realism in rendered scenes. Procedural texture basis functions, such as Perlin’s noise function, are often built on hash functions defined over the integer lattice. These hash functions are usually based on permutation tables and have a short period. This causes procedural textures to repeat. In this paper, we present a met...

We present three methods for texturing point models from sample textures. The first method, the point parameterization method, uses a fast distortion-bounded parameterization algorithm to flatten the point model’s surface into one or more 2D patches. The sample texture is mapped onto these patches and alpha blending is used to minimize the discontinuity in the gaps between the patches. The seco...

We address the problem of texturing flat surfaces by spray-painting through 3D printed stencils. We propose a system that (1) decomposes an image into alpha-blended layers; (2) computes a stippling given a transparency channel; (3) generates a 3D printed stencil given a stippling and (4) simulates the effects of spray-painting through the stencil.

Spectral Textures are rendered by multi-layer texturing, where each layer provides a certain band of spatial frequencies for the final texture. Transparency channels introduce statistical dependencies between the layers. Figures 1 shows series of screenshots that illustrate the multilayer approach of spectral texturing. The left column shows the single texture layers, increasing in scale from t...
