International Conference on Machine Learning and Cybernetics
作者: Xue, Q Zhang, ZQ Sun, JZ Tianjin Univ Dept Comp Sci & Technol Tianjin 300072 Peoples R China
To perform the image-based modeling (IBM) procedure, the parameters, inch as camera focus and principal point, are always needed by user input or by complicated calculation. A new computer vision based IBM method for ... 详细信息

Conference on Computer Vision and Pattern Recognition
作者: Favaro, P Osher, S Soatto, S Vese, L Washington Univ Dept Elect Engn St Louis MO 63130 USA
We cast the problem of inferring the 3D shape of a scene from a collection of defocused images in the framework of anisotropic diffusion. We propose a novel algorithm that can estimate the shape of a scene by inferrin... 详细信息

Proceedings of the 2003 symposium on Interactive 3D graphics
作者: Ryan M. Ismert Kavita Bala Donald P. Greenberg Cornell University
image-based modeling techniques permit the creation of visually interesting geometric models from photographs. But traditional image-based texturing (IBT) techniques often result in extracted textures of poor, uneven ... 详细信息

ACM TRANSACTIONS ON GRAPHICS 2003年 第3期22卷 759-769页
作者: Matusik, W Pfister, H Brand, M McMillan, L MIT Cambridge MA 02139 USA MERL Cambridge MA 02139 USA Univ N Carolina Chapel Hill NC USA
We present a generative model for isotropic bidirectional reflectance distribution functions (BRDFs) based on acquired reflectance data. Instead of using analytical reflectance models, we represent each BRDF as a dens... 详细信息

INTERNATIONAL JOURNAL OF COMPUTER VISION 2002年 第2期50卷 143-169页
作者: Pighin, F Szeliski, R Salesin, DH Univ So Calif Inst Creat Technol Los Angeles CA 90089 USA Microsoft Res Redmond WA USA Univ Washington Dept Comp Sci Seattle WA 98195 USA
We present a new set of techniques for modeling and animating realistic faces from photographs and videos. Given a set of face photographs taken simultaneously, our modeling technique allows the interactive recovery o... 详细信息

International Symposium on Computer Graphics, image Processing, and Vision (SIBGRAPI 98)
作者: Carvalho, PCP Szenberg, F Gattass, M Inst Matemat Pura & Aplicada BR-22460320 Rio De Janeiro Brazil
We present a two-step camera calibration process based on linear least squares formulations. We show how to apply this process to build an integrated modeling environment, in which a scene is modeled by having the use... 详细信息

Computer Graphics Annual Conference
作者: Debevec, P Hawkins, T Tchou, C Duiker, HP Sarokin, W Sagar, M Univ Calif Berkeley Div Comp Sci Berkeley CA 94720 USA
We present a method to acquire the reflectance field of a human face and use these measurements to render the face under arbitrary changes in lighting and viewpoint. We first acquire images of the face from a small se... 详细信息
