  • Overcoming the singularity problem in digital image restoration

    Creator:
    Osta, Ahmad M.
    Abstract:
    A recorded image is a degraded version of an original image. The process of removing the degradations is called restoration. Two types of degradations are considered in this thesis: namely, linear motion and defocused lens blurrings. Using the direct deconvolution technique to restore blurred images is impossible if the blurring...

  • Volume analysis and visualization

    Creator:
    Khare, Ankit
    Abstract:
    3D datasets acquire great importance in the context of medical imaging. In this thesis we survey and enhance solutions to problems inherently associated with 3D datasets-processing time,noise and visualization. Efforts include development of a tool kit to provide a multi-threaded processing platform to cut processing time, produce real time visualization...
