  • Inverse problems in image processing 

    Neelamani, Ramesh (2004)
    Inverse problems involve estimating parameters or data from inadequate observations; the observations are often noisy and contain incomplete information about the target parameter or data due to physical limitations of the ...
  • Wavelet-based deconvolution for ill-conditioned systems 

    Neelamani, Ramesh (1999)
    This thesis proposes a new approach to wavelet-based image deconvolution that comprises Fourier-domain system inversion followed by wavelet-domain noise suppression. In contrast to other wavelet-based deconvolution approaches, ...
