An algorithm for improving Non-Local Means operators via low-rank approximation
Victor May, Yosi Keller, Nir Sharon +1
We present a method for improving a Non Local Means operator by computing its low-rank approximation. The low-rank operator is constructed by applying a filter to the spectrum of t…

A global approach to the refinement of manifold data
Nira Dyn, Nir Sharon
A refinement of manifold data is a computational process, which produces a denser set of discrete data from a given one. Such refinements are closely related to multiresolution rep…

Manifold-valued subdivision schemes based on geodesic inductive averaging
Nira Dyn, Nir Sharon
Subdivision schemes have become an important tool for approximation of manifold-valued functions. In this paper, we describe a construction of manifold-valued subdivision schemes f…
