    • Automatic determination of navigable areas, pedestrian detection, and augmentation of virtual agents in real crowd videos 

      Doğan, Yalım (Bilkent University, 2018-12)
      Crowd simulations imitate the behavior of crowds and individual agents in the crowd with personality and appearance, which determines the overall model of a multi-agent system. In such studies, the models are often ...

    • Content-based retrieval of historical Ottoman documents stored as textual images 

      Şaykol, E.; Sinop, A. K.; Güdükbay U.; Ulusoy, Ö.; Çetin, A. E. (IEEE, 2004)
      There is an accelerating demand to access the visual content of documents stored in historical and cultural archives. Availability of electronic imaging tools and effective image processing techniques makes it feasible to ...

    • Creating a presentation format of interactive media for innovative products 

      Sinman, Aslı (Bilkent University, 1994)
      In this work, an interactive presentation format to give information about an innovative product is developed. Innovation process is also discussed for communication of users and designers. Accessing the original needs ...

    • Direct volume rendering of unstructured grids 

      Berk, H.; Aykanat, C.; Güdükbay U. (Pergamon Press, 2003)
      This paper investigates three categories of algorithms for direct volume rendering of unstructured grids, which are image-space, object-space, and hybrid methods. We propose three new algorithms. Cell Projection algorithm, ...

    • Fast ray tracing 3D models 

      Işler V.; Özgüç, B. (1991)
      In many computer graphics applications such as CAD, realistic displays have very important and positive effects on the users of the system. There are several techniques to generate realistic images with the computer. Ray ...

    • Graph visualization toolkits 

      Dogrusoz, U.; Feng, Q.; Madden, B.; Doorley, M.; Frick, A. (IEEE, 2002)
      The Graph Layout Toolkit and Graph Editor Toolkit, which provide a framework for graph visualization useful in a broad array of application areas are introduced. As such, an architectural overview of these tools is presented ...

    • Hair motion simulation 

      Sahillioğlu, Y.; Özgüç, B. (Springer, 2004)
      Hair motion simulation in computer graphics has been an attraction for many researchers. The application we have developed has been inspired by the related previous work as well as our own efforts in finding useful algorithms ...

    • A parallel progressive radiosity algorithm based on patch data circulation 

      Aykanat, C.; Çapin, T. K.; Özgüç, B. (Pergamon Press, 1996)
      Abstract - Current research on radiosity has concentrated on increasing the accuracy and the speed of the solution. Although algorithmic and meshing techniques decrease the execution time, still excessive computational ...

    • PATIKA: An integrated visual environment for collaborative construction and analysis of cellular pathways 

      Demir, E.; Babur, O.; Dogrusoz, U.; Gursoy, A.; Nisanci, G.; Cetin Atalay, R.; Ozturk, M. (Oxford University Press, 2002)
      Motivation: Availability of the sequences of entire genomes shifts the scientific curiosity towards the identification of function of the genomes in large scale as in genome studies. In the near future, data produced about ...

    • Right-triangular subdivision for texture mapping ray-traced objects 

      Akdemir, U.; Özgüç, B.; Güdükbay U.; Selçuk, A. (Springer, 1998)
      The introduction of global illumination and texture mapping enabled the generation of high-quality, realistic looking images of computer graphics models. We describe a fast and efficient 2D texture mapping algorithm that ...

    • A spring force formulation for elastically deformable models 

      Güdükbay U.; Özgüç, B.; Tokad, Y. (Pergamon Press, 1997)
      Continuous deformable models are generally represented using a grid of control points. The elastic properties are then modeled using the interactions between these points. The formulations based on elasticity theory express ...

    • Stereoscopic view-dependent visualization of terrain height fields 

      Güdükbay U.; Yilmaz, T. (IEEE, 2002)
      Visualization of large geometric environments has always been an important problem of computer graphics. In this paper, we present a framework for the stereoscopic view-dependent visualization of large scale terrain models. ...
