Neighborhood filters and PDE's
Denoising images can be achieved by a spatial averaging of nearby pixels. However, although this method removes noise it creates blur. Hence, neighborhood filters are usually preferred. These filters perform an average of neighboring pixels, but only under the condition that their grey level is close enough to the one of the pixel in restoration. This very popular method unfortunately creates s...
متن کاملDecreasing rearrangement and a fuzzy variational problem
In this note we introduce a variational problem with respect to an integrable fuzzy set f . The energy functional is maximized over a deleted σ -algebra. Using the decreasing rearrangement of f we prove that the admissible set can be replaced by the more convenient set of cuts of f . Finally an special case is considered where the variational problem can be transformed into a one dimensional se...
متن کاملSymmetric Decreasing Rearrangement Is Sometimes Continuous
This paper deals with the operation .9R 'of symmetric decreasing re-arrangement which maps Wl,p (Rn) to Wi ,p (Rn) . We show that even thoughit is norm decreasing, .9R is not continuous for n ~ 2. The functions at which.9R is continuous are precisely characterized by a new property called co-arearegularity. Every sufficiently differentiable function is co-area regular, and both<...
متن کاملExploring collaborative filters: Neighborhood-based approach
In this project, we study the effectiveness of collaborative filtering mechanisms in the context of the Netflix competition. We focus our attention on a dataset provided by Netflix which includes a training set with more than 100 million 4-tuples: user id, movie id, rating, and date [3]. In the first part of this project, we develop a simple model to predict future ratings of users based on the...
متن کاملA decreasing rearrangement for functions on homogeneous trees
We introduce a new decreasing rearrangement for functions defined on a homogeneous tree, which enjoys very intuitive and natural properties. The idea is to iterate, with respect to a particular ordering, the usual one dimensional rearrangement on each geodesic. After showing the canonicity of this definition and the axioms of symmetrization, we prove our main result: the geometric and analytic ...
