  • Delaunay Triangulation Based 3D Human Face Modeling From Uncalibrated İmages 
    Hassanpour, Reza; Atalay, Volkan (IEEE Computer Society, 2004)
    In this paper, we describe an algorithm for generating three dimensional models of human faces from uncalibrated images. Input images are taken by a camera generally with a small rotation around a single axis which may ...
  • Digital Video Stabilization Using Radon Transform 
    Babagholami-Mohamadabadi, Behnam; Bagheri-Khaligh, Ali; Hassanpour, Reza (IEEE, 2012)
    Digital video stabilization is a category of techniques used to reduce the impact of unintentional camera motion such as jitter, jiggle, and other unsteady motions. These unintentional shakings degrade visual quality of ...
  • Experimental study on the sensitivity of autocalibration to projective camera model parameters 
    Hassanpour, Reza; Atalay, Volkan (Spie-Int Society Optical Engineering, 2006-04)
    Existing methods of 3-D object modeling and recovering 3-D data from uncalibrated 2-D images are subject to errors introduced by assumptions about camera parameters and mismatches in finding point pairs in the images. In ...
  • Head Modeling with Camera Auto-calibration and Deformation 
    Hassanpour, Reza; Atalay, Volkan (2002)
    A 3D head modeling method from a sequence of 2D images is described. The views from which the input images are acquired are not calibrated. Therefore, an auto-calibration method for a sequence of images with small ...
  • Head Modeling with Camera Autocalibration and Deformation. 
    Hassanpour, Reza; Atalay, Mehmet Volkan (2002-01)
  • Human face identification using M-PCA augmented with Gabor Wavelet 
    Karaömeroǧlu, Betül; Hassanpour, Reza (2005-11)
    In this paper, a specialized version of PCA augmented with Gabor Wavelet Transform is proposed for face identification. Firstly, to cope with the variations due to illumination and facial expression changes 2D Gabor Wavelet ...
  • Hybrid Expert Systems: A Survey of Current Approaches and Applications 
    Şahin, S.; Tolun, Mehmet R.; Hassanpour, Reza (Expert Systems With Applications, 2012-03)
    This paper is a statistical analysis of hybrid expert system approaches and their applications but more specifically connectionist and neuro-fuzzy system oriented articles are considered. The current survey of hybrid expert ...
