Edge detector tolerant to object defocusing
(Elsevier Science, 2010-10)
Different methods for edge extraction have been studied in the past years. In a recent paper we have presented a rotation-invariant edge extractor based on a spiral phase filter placed in the frequency plane of a convergent ...
Non-random food-web assembly at habitat edges increases connectivity and functional redundancy.
(Ecological Society of America, 2017-03)
Habitat fragmentation dramatically alters the spatial configuration of landscapes, with the creation of artificial edges affecting community structure and dynamics. Despite this, it is not known how the different food webs ...
SherlockFog: a new tool to support application analysis in Fog and Edge computing
(Springer, 2019-05)
The Fog and Edge Computing paradigms have emerged as a solution to limitations of the Cloud Computing model to serve a huge amount of connected devices efficiently. These devices have unused computing power that could be ...
Edge effects on insect-plant food webs: Assessing the influence of geographical orientation and microclimatic conditions
(Wiley Blackwell Publishing, Inc, 2020-02)
1. Geographical orientation affects the magnitude of microclimatic edge effects, mainly by altering the exposure to solar radiation. There is considerable evidence about the influence of microclimatic edge effects on ...
On the performance of Some Edge Detectors for Gray Scale Images
(Old City Publishing Inc, 2019-03)
Image processing represents an important challenge in different fields. Mathematical Morphology uses concepts from set theory, geometry, algebra and topology to analyze the geometrical structure of an image. Using them, ...
A characterization of edge-perfect graphs and the complexity of recognizing some combinatorial optimization games
(Elsevier Science, 2013-02)
We characterize edge-perfect graphs and prove that it is co-NP-complete to recognize them. In consequence, recognizing the defining matrices of totally balanced packing games is also co-NP-complete, in contrast with the ...
Super-resolved edge detection in optical microscopy images by superposition of virtual point sources
(Optical Society of America, 2020-08)
A new approach to the edge detection problem is presented which is specially designed to achieve high accuracy detection, below instrumental resolution (super resolution) in microscopy images. The method is based in a ...
Smoke detection for static cameras
(01/28/2015)
This paper describes the smoke detection for static cameras. The background subtraction was used to determine moving objects. Color characteristics were utilized to distinguish smoke regions and other scene members. Separate ...
Modelling and solving the perfect edge domination problem
(Springer Heidelberg, 2018-10)
A formulation is proposed for the perfect edge domination problem and some exact algorithms based on it are designed and tested. So far, perfect edge domination has been investigated mostly in computational complexity ...
