Representation and Coding of Signal Geometry
Petros T Boufounos, Shantanu Rane, Hassan Mansour
Approaches to signal representation and coding theory have traditionally focused on how to best represent signals using parsimonious representations that incur the lowest possible…
Learning optimal nonlinearities for iterative thresholding algorithms
Ulugbek S. Kamilov, Hassan Mansour
Iterative shrinkage/thresholding algorithm (ISTA) is a well-studied method for finding sparse solutions to ill-posed inverse problems. In this letter, we present a data-driven sche…
Guided Signal Reconstruction with Application to Image Magnification
Akshay Gadde, Andrew Knyazev, Dong Tian +1
We study the problem of reconstructing a signal from its projection on a subspace. The proposed signal reconstruction algorithms utilize a guiding subspace that represents desired…
Chebyshev and Conjugate Gradient Filters for Graph Image Denoising
Dong Tian, Hassan Mansour, Andrew Knyazev +1
In 3D image/video acquisition, different views are often captured with varying noise levels across the views. In this paper, we propose a graph-based image enhancement technique th…
