• Behavioral analysis of anisotropic diffusion in image processing 

      You, Yu-Li; Xu, Wenyuan; Tannenbaum, Allen R.; Kaveh, Mostafa (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 1996-11)
      In this paper, we analyze the behavior of the anisotropic diffusion model of Perona and Malik (1990). The main idea is to express the anisotropic diffusion equation as coming from a certain optimization problem, so its ...
    • Color histogram equalization through mesh deformation 

      Pichon, Eric; Niethammer, Marc; Sapiro, Guillermo (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2003-09)
      In this paper we propose an extension of grayscale histogram equalization for color images. For aesthetic reasons, previously proposed color histogram equalization techniques do not generate uniform color histograms. Our ...
    • Experiments on geometric image enhancement 

      Sapiro, Guillermo; Tannenbaum, Allen R.; You, Yu-La; Kaveh, Mos (Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 1994-11)
      In this paper we experiment with geometric algorithms for image smoothing. Examples are given for MRI and ATR data. We emphasize experiments with the affine invariant geometric smoother or affine heat equation, originally ...
    • Multiscale and meta-analytic approaches to inference in clinical healthcare data 

      Hamilton, Erin Kinzel (Georgia Institute of Technology, 2013-03-29)
      The field of medicine is regularly faced with the challenge of utilizing information that is complicated or difficult to characterize. Physicians often must use their best judgment in reaching decisions or recommendations ...
