Scheirer Anderson Rocha Universidade Estadual de Campinas Campinas SP BR Dept. of Mathematics and Computer Science Skidmore College Saratoga Springs NY USA Securics Inc. University of Colorado Colorado Springs CO USA Institute of Computing University of Campinas (UNICAMP) Campinas São Paulo Brazil
Similar to ballistic tests in which we match a gun to its bullets, we can identify a given digital camera that acquired an image under investigation. In this paper, we discuss a method for identifying whether or not a... 详细信息

brazilian symposium on computer graphics and image processing (SIBGRAPI)
作者: Raissa T. Vieira Carlos Eduardo de Oliveira Chierici Carolina T. Ferraz Adilson Gonzaga Department of Electrical Engineering University of São Paulo São Paulo Brazil Universidade de Sao Paulo Sao Paulo São Paulo BR
This paper proposes a new methodology for micro pattern analysis in digital images based on fuzzy numbers. A micro-pattern is the structure of the gray-level pixels within a neighborhood and can describe the spatial c... 详细信息

作者: Eduardo Ceretta Dalla Favera Waldemar Celes Computer Science Department Pontifical Catholic University of Rio de Janeiro Tecgraf/PUC-Rio Brazil
Ambient occlusion is a low-cost technique to simulate indirect ambient illumination in a realistic way. The goal is to estimate the amount of incident ambient light at each visible point. In this paper, we propose a n... 详细信息
