Image Denoising via Correlation Based Sparse Representation and Dictionary Learning

Baloch, Gulsher Lund (Eastern Mediterranean University EMU - Doğu Akdeniz Üniversitesi (DAÜ), 2018-01)

Error-based Orthogonal Matching Pursuit (OMPe) employed in many image denoising algorithms (e.g., K-means Singular Value Decomposition (K-SVD) algorithm) tries to reconstruct the clean image patch by projecting the ...
Sparse Representation over Multiple Learned Dictionaries via the Gradient Operator Properties with Application to Single-Image Super-Resolution

Yeganli, Faezeh (Eastern Mediterranean University (EMU) - Doğu Akdeniz Üniversitesi (DAÜ), 2015-12)

Single-image super-resolution is an ill-posed inverse problem that requires effective regularization. Super-resolution over learned dictionaries offers a successful framework for efficiently solving this problem exploiting ...
