A Convolutional Neural Network for the automatic diagnosis of collagen VI-related muscular dystrophies
(2019-12-01)
Article
Restricted access - publisher's policyThe development of machine learning systems for the diagnosis of rare diseases is challenging, mainly due to the lack of data to study them. This paper surmounts this obstacle and presents the first Computer-Aided Diagnosis ... -
Closed-form position analysis of variable geometry trusses
(2017-03-01)
Article
Open AccessVariable geometry trusses are composed, in general, of unit cells which can be modeled as bars connected by spherical joints. Under mild conditions, it has been shown that the only feasible cells are topologically equivalent ... -
Uncalibrated visual servo for unmanned aerial manipulation
(Institute of Electrical and Electronics Engineers (IEEE), 2017-08-01)
Article
Open AccessThis paper addresses the problem of autonomous servoing an unmanned redundant aerial manipulator using computer vision. The overactuation of the system is exploited by means of a hierarchical control law, which allows to ... -
New algebraic conditions for the identification of the relative position of two coplanar ellipses
(2017-05-01)
Article
Open AccessThe identification of the relative position of two real coplanar ellipses can be reduced to the identification of the nature of the singular conics in the pencil they define and, in general, their location with respect to ... -
On Cayley's factorization of 4D rotations and applications
(2017-03-01)
Article
Open AccessA 4D rotation can be decomposed into a left- and a right-isoclinic rotation. This decomposition, known as Cayley’s factorization of 4D rotations, can be performed using the Elfrinkhof–Rosen method. In this paper, we present ... -
A bayesian approach to simultaneously recover camera pose and non-rigid shape from monocular images
(2016)
Article
Open AccessIn this paper we bring the tools of the Simultaneous Localization and Map Building (SLAM) problem from a rigid to a deformable domain and use them to simultaneously recover the 3D shape of non-rigid surfaces and the sequence ... -
Sensor localization from distance and orientation constraints
(2016)
Article
Open AccessThe sensor localization problem can be formalized using distance and orientation constraints, typically in 3D. Local methods can be used to refine an initial location estimation, but in many cases such estimation is not ... -
A matrix-based approach to the image moment problem
(2006-11)
Article
Open AccessAn image can be seen as an element of a vector space and hence it can be expressed in as a linear combination of the elements of any non necessarily orthogonal basis of this space. After giving a matrix formulation of this ... -
Geometric path planning without maneuvers for nonholonomic parallel orienting robots
(Institute of Electrical and Electronics Engineers (IEEE), 2016-07)
Article
Open AccessCurrent geometric path planners for nonholonomic parallel orienting robots generate maneuvers consisting of a sequence of moves connected by zero-velocity points. The need for these maneuvers restrains the use of this kind ... -
Path planning for active tensegrity structures
(2016-01-01)
Article
Open AccessThis paper presents a path planning method for actuated tensegrity structures with quasi-static motion. The valid configurations for such structures lay on an equilibrium manifold, which is implicitly defined by a set of ... -
Planning wrench-feasible motions for cable-driven hexapods
(2016-04-01)
Article
Open AccessMotion paths of cable-driven hexapods must carefully be planned to ensure that the lengths and tensions of all cables remain within acceptable limits, for a given wrench applied to the platform. The cables cannot go slack-to ... -
Variable symmetry breaking in numerical constraint problems
(2015)
Article
Open AccessSymmetry breaking has been a hot topic of research in the past years, leading to many theoretical developments as well as strong scaling strategies for dealing with hard applications. Most of the research has however focused ...
