An ever-growing number of real-world computer vision applications require classification,
segmentation, retrieval, or realistic rendering of genuine materials. However, the …

In these lecture notes, the authors have outlined several approaches to solve a NMF/NTF
problem. The following main conclusions can be drawn: 1) Multiplicative algorithms are not …

Abstract The Bidirectional Reflectance Distribution Function (BRDF) describes the
appearance of a material by its interaction with light at a surface point. A variety of analytical …

Texture analysis is a very important area in the field of computer vision and related fields.
There are a good number of databases developed by different research groups for various …

Virtual Humans provides a much-needed definition of what constitutes a 'virtual human'and
places virtual humans within the wider context of Artificial Intelligence development. It …

Stone is widespread in its use as a building material and artistic medium. One of its most
remarkable qualities is that it changes appearance as it interacts with the environment …

Abstract The Bidirectional Texture Function (BTF) is a data‐driven solution to render
materials with complex appearance. A typical capture contains tens of thousands of images …

Using the framework, we systematically compare several types of microappearance models.
We acquired computed microtomography (micro CT) scans of several fabrics, photographed …

This paper introduces a tensor framework for image-based rendering. In particular, we
develop an algorithm called TensorTextures that learns a parsimonious model of the …

Algorithms for scene understanding and realistic image synthesis require accurate models
of the way real-world materials scatter light. This study describes recent work in the graphics …
