Three-dimensional geometric models have been used to present architectural and engineering works, showing their final configuration. But, when the clarification of a detail or the constitution of a construction step in needed, these models are not appropriate because they do not allow the observation of the construction activity. Models that could present dynamically changes of the building geo...

background: medical image interpolation is recently introduced as a helpful tool to obtain further information via initial available images taken by tomography systems. this information may be useful for better diagnosis of possible lesions or better tumor delineation at radiation treatment. to do this, deformable image registration algorithms are mainly utilized to perform image interpolation ...

Registration (or alignment) of surfaces is an important task in many areas such as robotics, computer aided modeling, virtual reality and surface reconstruction. Building a full model of a object requires registering multiple surfaces observed from different viewpoints. In this paper we present an approach robust to outliers, for registering multiple surfaces simultaneously when the transformat...

Establishing a regulation regarding information and electronic transactions (ITE), which aims to develop Information Technology, can be carried out optimally, evenly, spread all levels of society educate the nation's life. an Electronic-Based Government System (SPBE) realize clean, effective, transparent, accountable governance, quality, reliable public services. The Lampung Provincial has made...

Recently modern non-Euclidean structure and motion estimation methods have been incorporated into augmented reality scene tracking and virtual object registration. We present a study of how the choice of projective, affine or Euclidean scene viewing geometry and similarity, affine or homography based object registration affects how accurately a virtual object can be overlaid in scene video from...

Virtual Reality techniques were used to develop educational didactic models in the area of Civil Engineering. The visualization of the distinct physical steps of a construction is shown in the virtual applications here presented. The developed models bring new perspectives in the teaching activity as a support to expose new curricular programmes or complex sequence construction. In order to obt...
