brazilian symposium on computer graphics and image processing (SIBGRAPI)
作者: A.X. Falcao F.P.G. Bergo P.A.V. Miranda Institute of Computing State University of Campinas Sao Paulo Brazil
the image foresting transform (IFT) has been proposed for the design of image operators based on connectivity. the IFT reduces image processing problems into a minimum-cost path forest problem in a graph derived from ... 详细信息

brazilian symposium on computer graphics and image processing (SIBGRAPI)
作者: H. Mayer Computer Graphics and Vision Graz University of Technology Graz Austria
We present a method to measure reflectance and texture of surfaces in a one step process. For later use in digital image synthesis, it is mandatory to separate the gathered intensity values into these two parts to eli... 详细信息
