First low frequency all-sky search for continuous gravitational wave signals
(Amer Physical Soc, 2016-02-25)
In this paper we present the results of the first low frequency all-sky search of continuous gravitational wave signals conducted on Virgo VSR2 and VSR4 data. The search covered the full sky, a frequency range between 20 ...

Counting objects in images is a pattern recognition problem that focus on identifying an element to determine its incidence. Approached in the literature as Visual Object Counting (VOC), such application can be very precise. ...
Seta: ambiente de realidade aumentada para o ensino de algoritmos de aprendizagem de máquina
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Informática, 2013-12-19)
Augmented reality (AR) is the overlay of virtual images into images of a real
environment, in real time. AR environments can be used as supplementary teaching resources for different content . This paper presents an ...
Circle detection on images using learning automata
(2012)
Circle detection over digital images has received considerable attention from the computer vision community over the last few years devoting a tremendous amount of research seeking for an optimal detector. This article ...
Automatic circle detection on images based on an evolutionary algorithm that reduces the number of function evaluations
(2013)
This paper presents an algorithm for the automatic detection of circular shapes from complicated and noisy images with no consideration of the conventional Hough transform principles. The proposed algorithm is based on a ...
Multi-circle detection on images inspired by collective animal behavior
(2013)
Hough transform (HT) has been the most common method for circle detection that delivers robustness but adversely demands considerable computational efforts and large memory requirements. As an alternative to HT-based ...
Circle detection using electro-magnetism optimization
(2012)
Nature-inspired computing has yielded remarkable applications of collective intelligence which considers simple elements for solving complex tasks by common interaction. On the other hand, automatic circle detection in ...
Multi-circle detection on images using artificial bee colony (ABC) optimization
(2012)
Hough transform has been the most common method for circle detection, exhibiting robustness, but adversely demanding considerable computational effort and large memory requirements. Alternative approaches include heuristic ...
