Extracting Realistic Textures from Reference Spheres
نویسندگان
چکیده
This paper proposes a method for extracting realistic textures from real-world reference spheres. The BRDF parameters of fundamental materials, as well as a material weight map for the sphere are obtained through a non-linear optimization process. The material weight map can be used as a conventional texture for relighting. With the BRDF models recovered, the real and natural appearances of 3D objects can be reproduced under novel lighting and viewing directions.

Integration of Voxel Colouring Technique in the Volumetric Textures Representation Based on Image Layers Babahenini
This paper presents a method for integrating a technique of reconstruction scene (voxel colouring) starting from images of the reference element of a volumetric texture, this one will be converted in a second phase into a whole of layers (2D images considered as transparent textures), which will be projected and composed successively on surface defined as volumetric grid using the Zbuffer algor...
متن کاملBoundary conditions for textures and defects
2014 We study the influence of boundary conditions on the existence and coexistence of distortions (textures, defects) in ordered media. The standard topological classification is based on mappings from spheres into the manifold of internal states (characterizing the order). For periodic, or partly periodic boundary conditions, the spheres have to be replaced by tori, or quasitori. The modifica...
متن کاملManifold Regularized Slow Feature Analysis for Dynamic Texture Recognition
Dynamic textures exist in various forms, e.g., fire, smoke, and traffic jams, but recognizing dynamic texture is challenging due to the complex temporal variations. In this paper, we present a novel approach stemmed from slow feature analysis (SFA) for dynamic texture recognition. SFA extracts slowly varying features from fast varying signals. Fortunately, SFA is capable to leach invariant repr...
متن کاملDynamic Texture Recognition Using Normal Flow and Texture Regularity
The processing, description and recognition of dynamic (time-varying) textures are new exciting areas of texture analysis. Many real-world textures are dynamic textures whose retrieval from a video database should be based on both dynamic and static features. In this article, a method for extracting features revealing fundamental properties of dynamic textures is presented. These features are b...
متن کاملQualitative Characterization of Dynamic Textures for Video Retrieval
A new issue in texture analysis is its extension to temporal domain, known as dynamic texture. Many real-world textures are dynamic textures whose retrieval from a video database should be based on both dynamic and static features. In this article, a method for extracting features revealing fundamental properties of dynamic textures is presented. Their interpretation enables qualitative request...
