Image restoration and reconstruction using projections onto epigraph set of convex cost fuchtions
(Bilkent University, 2015)This thesis focuses on image restoration and reconstruction problems. These inverse problems are solved using a convex optimization algorithm based on orthogonal Projections onto the Epigraph Set of a Convex Cost functions ... -
A novel compression algorithm based on sparse sampling of 3-D laser range scans
(Bilkent University, 2010)3-D models of environments can be very useful and are commonly employed in areas such as robotics, art and architecture, environmental planning and documentation. A 3-D model is typically comprised of a large number of ... -
Signal representation and recovery under measurement constraints
(Bilkent University, 2012)We are concerned with a family of signal representation and recovery problems under various measurement restrictions. We focus on finding performance bounds for these problems where the aim is to reconstruct a signal ...
