Multi-component separation, inpainting and denoising with recovery guarantees
Van Tiep Do
In image processing, problems of separation and reconstruction of missing pixels from incomplete digital images have been far more advanced in past decades. Many empirical results…
An asymptotic analysis of separating pointlike and -curvelike singularities
Van Tiep Do, Alex Goeßmann
In this paper, we present a theoretical analysis of separating images consisting of pointlike and -curvelike structures, where . Our approach is based on …
Analysis of simultaneous inpainting and geometric separation based on sparse decomposition
Van Tiep Do, Ron Levie, Gitta Kutyniok
Natural images are often the superposition of various parts of different geometric characteristics. For instance, an image might be a mixture of cartoon and texture structures. In…
Broadband Homonuclear Decoupling
Van Do, Navin Khaneja
We present a solution to the problem of broadband decoupling of a coupled homonuclear two-spin system. We describe a pulse sequence that creates an effective field perpendicular to…
