    One of the challenging advents in computer science in recent years was the fast evolution of parallel processors, specially the GPU - graphics processing unit. GPUs today play a major role in many computational environments, most notably those regarding real-time graphics applications, such as games. The digital game industry is one of the main driving forces behind GPUs, it persistently elevates ... View full abstract»

  • Geometric Algebra: A Powerful Tool for Solving Geometric Problems in Visual Computing

    Publication Year: 2009, Page(s):17 - 30

    Geometric problems in visual computing (computer graphics, computer vision, and image processing) are typically modeled and solved using linear algebra (LA). Thus, vectors are used to represent directions and points in space, while matrices are used to model transformations. LA, however, presents some well-known limitations for performing geometric computations. As a result, one often needs to agg... View full abstract»

  • Multiscale Methods for Image Processing: The Wavelet and the Scale-Space Approaches

    Publication Year: 2009, Page(s):31 - 44

    Multiscale approaches have been largely considered in several signal processing applications. They play an important role when designing automatic methods to cope with real world measurements where, in most of the cases, there is no prior information about which would be the appropriate scale. The basic idea behind a multiscale analysis is to embed the original signal into a family of derived sign... View full abstract»

    This tutorial is intended for programmers who are interested in boosting their graphics application using a different architectural paradigm: the cell broadband engine (Cell BE). Our main idea is to focus on performance issues that can be efficiently handled by the multicore and vector facilities of the Cell BE. We aim to offer to programmers an alternative way for high-performance graphics rather... View full abstract»

    Imaging systems, particularly those on board satellites, provide a repetitive and consistent view of the earth that has been used in many remote sensing applications such as urban growth, deforestation and crop monitoring, weather prediction, land use mapping, land cover mapping and so on. For each application it is necessary to develop a specific methodology to extract information from the image ... View full abstract»

    Local descriptors have been extensively used in CBIR systems, where their robustness to intense geometric and photometric transformations allows the identification of a target object/image with great reliability. However, due to their excessive discriminating power, their application to the retrieval of complex categories is challenging. The introduction of the technique of visual dictionaries (al...
