  • Attentive visual motion processing: computations in the log-polar plane  
  • by Kostas Daniilidis — 1995 — Accepted in "Computing, Archives for Informatic and Numerical Computation
  • …Attentive vision is characterized by selective sensing in space and time as well as selective processing with respect to a speci c task. Selection in space involves the splitting of the visual eld in a high resolution area- the fovea- and a space-variant resolution area-the periphery. Both in neurob…

  • Conformal Rectification of Omnidirectional Stereo Pairs  
  • by Christopher Geyer Kostas, Kostas Daniilidis — 2003 — in Omnivis 2003: Workshop on Omnidirectional Vision and Camera Networks
  • …A pair of stereo images are said to be rectified if corresponding image points have the same y-coordinate in their respective images. In this paper we consider the rectification of two omnidirectional cameras, specifically two parabolic catadioptric cameras. Such systems consist of a parabolic mirro…

  • Mirrors in motion: Epipolar geometry and motion estimation  
  • by Christopher Geyer Kostas, Kostas Daniilidis — 2003 — In International Journal on Computer Vision
  • …In this paper we consider the images taken from pairs of parabolic catadioptric cameras separated by discrete motions. Despite the nonlinearity of the projection model, the epipolar geometry arising from such a system, like the perspective case, can be encoded in a bilinear form, the catadioptric fu…

  • Linear Solutions for Visual Augmented Reality Registration £  
  • by Adnan Ansar, Kostas Daniilidis
  • …Correct registration of virtual objects into real scenes requires robust estimation of camera pose. Since most augmented reality applications also require real-time performance in potentially restricted environments with no a priori motion model, we seek pose estimation algorithms which are fast, pe…

  • Omnidirectional Video  
  • by Christopher Geyer, Kostas Daniilidis — 2003 — Visual Computer
  • …Omnidirectional video enables direct surround immersive viewing of a scene by warping the original image into the correct perspective given a viewing direction. However, novel views from viewpoints off the camera path can only be obtained if we solve the 3D motion and calibration problem. In this…

  • Real Time Trinocular Stereo For Tele-Immersion  
  • by Jane Mulligan, Kostas Daniilidis — 2001
  • …Tele-immersion is a technology that augments your space with real-time 3D projections of remote spaces thus facilitating the interaction of people from different places in virtually the same environment. Tele-immersion combines 3D scene recovery from computer vision, and rendering and interaction fr…

  • Optical Flow Computation in the Log-Polar Plane  
  • by Kostas Daniilidis, Volker Krüger — 1995 — in Proc. Int. Conf. on computer analysis of images and patterns CAIP
  • …: Vision systems with spatially homogeneous resolution are not able to provide a real time response in a dynamically changing environment. A reactive behavior necessitates selective sensing in space. Such a selection can be accomplished by the combination of a space-variant resolution scheme and a …

  • Trinocular Stereo for Non-Parallel Configurations  
  • by Jane Mulligan, Kostas Daniilidis — 2000 — In Proceedings of the 15th International Conference on Pattern Recognition
  • …The constraint of a third camera in stereo vision is a useful tool for reducing ambiguity in matching. Most of the systems using trinocular stereo to date however, have used configurations where the image planes of all three cameras are coplanar, or can be rectified to be so. In this paper we explor…

  • Constrained Self-Calibration  
  • by Jeffrey Mendelsohn, Kostas Daniilidis — 1999 — In Proc. IEEE Int. Conf. on Computer Vision and Pattern Recognition
  • …This paper focuses on the estimation of the intrinsic camera parameters and the trajectory of the camera from an image sequence. Intrinsic camera calibration and pose estimation are the prerequisites for many applications involving navigation tasks, scene reconstruction, and merging of virtual and r…

  • Properties of the Catadioptric Fundamental Matrix  
  • by Christopher Geyer, Kostas Daniilidis — 2002 — In Proc. Seventh European Conference on Computer Vision
  • …The geometry of two uncalibrated views obtained with a parabolic catadioptric device is the subject of this paper. We introduce the notion of circle space, a natural representation of line images, and the set of incidence preserving transformations on this circle space which happens to equal the …
