Total Variation for Image Denoising Based on a Novel Smart Edge Detector: An Application to Medical Images
(
Springer New York LLC
, 2019 , Article)
In medical imaging applications, diagnosis relies essentially on good quality images. Edges play a crucial role in identifying features useful to reach accurate conclusions. However, noise can compromise this task as it ...
Multiple Relay Selection and Beamforming in Dual-Hop Amplify-and-Forward Relay Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
In this paper, the problems of multiple relay selection and beamforming optimization are considered for a dual-hop amplify-and-forward relaying network under individual and total power constraints. The selection is performed ...
LaCoDa: Layered connected topology for massive data centers
(
Academic Press
, 2017 , Article)
One of the fundamental challenges of existing data centers is to design a network that interconnects massive number of servers, and therefore providing an efficient and fault-tolerant routing service to upper-layer ...
Cluster validity index based on Jeffrey divergence
(
Springer London
, 2017 , Article)
Cluster validity indexes are very important tools designed for two purposes: comparing the performance of clustering algorithms and determining the number of clusters that best fits the data. These indexes are in general ...
Re-parameterization reduces irreducible geometric constraint systems
(
Elsevier Ltd
, 2016 , Article)
You recklessly told your boss that solving a non-linear system of size n (n unknowns and n equations) requires a time proportional to n, as you were not very attentive during algorithmic complexity lectures. So now, you ...
Computation of Yvon-Villarceau circles on Dupin cyclides and construction of circular edge right triangles on tori and Dupin cyclides
(
Elsevier Ltd
, 2014 , Article)
Ring Dupin cyclides are non-spherical algebraic surfaces of degree four that can be defined as the image by inversion of a ring torus. They are interesting in geometric modeling because: (1) they have several families of ...
An improved star test for implicit polynomial objects
(
Elsevier Ltd
, 2016 , Article)
For a given point set, a particular point is called a star if it can see all the boundary points of the set. The star test determines whether a candidate point is a star for a given set. It is a key component of some ...
Multispectral image denoising with optimized vector non-local mean filter
(
Elsevier Inc.
, 2016 , Article)
Nowadays, many applications rely on images of high quality to ensure good performance in conducting their tasks. However, noise goes against this objective as it is an unavoidable issue in most applications. Therefore, it ...
