作者: S.J.F. Guimaraes A. De Albuquerque Araujo G. Cerqueira Departamento de Ciência da Computacao NPDI/DCC/UFMG Belo Horizonte Minas Gerais Brazil
Because of their storage conditions, old movies may present different defect types of different shapes and sizes. We propose a method for old movie restoration using opening by surface which eliminates image informati... 详细信息

作者: Favera, Eduardo Ceretta Dalla Celes, Waldemar Tecgraf/PUC-Rio Computer Science Department Pontifical Catholic University of Rio de Janeiro 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
