Swarm-based descriptor combination and its application for image classification
(2014)
In this paper, we deal with the descriptor combination problem in image classification tasks. This problem refers to the definition of an appropriate combination of image content descriptors that characterize different ...
Developing descriptors to predict mechanical properties of nanotubes
(2013-04-22)
Descriptors and quantitative structure property relationships (QSPR) were investigated for mechanical property prediction of carbon nanotubes (CNTs). 78 molecular dynamics (MD) simulations were carried out, and 20 descriptors ...
Fractal descriptors for discrimination of microscopy images of plant leaves
(2014)
This study proposes the application of fractal descriptors method to the discrimination of microscopy images of plant leaves. Fractal descriptors have demonstrated to be a powerful discriminative method in image analysis, ...
QSPR models of boiling point, octanol-water partition coefficient and retention time index of polycyclic aromatic hydrocarbons
(Elsevier Science BvAmsterdamHolanda, 2003)
Development of a new topological index for the prediction of normal boiling point temperatures of hydrocarbons: The Fi index
(Elsevier Science BvAmsterdamHolanda, 2012)
Recursive linear estimation for general discrete-time descriptor systems
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
This paper considers the optimal linear estimates recursion problem for discrete-time linear systems in its more general formulation. The system is allowed to be in descriptor form, rectangular, time-variant, and with the ...
Characterization of nanostructured material images using fractal descriptors
(ElsevierAmsterdam, 2013-04)
This work presents a methodology to the morphology analysis and characterization of nanostructured material images acquired from FEG-SEM (Field Emission Gun-Scanning Electron Microscopy) technique. The metrics were extracted ...
Propriedades químico-quânticas empregadas em estudos das relações estrutura-atividade
(Sociedade Brasileira de Química, 2010)
In this work we show that structure-activity relationship studies are of great importance in modern chemistry and biochemistry. In order to obtain a significant correlation, it is crucial that appropriate descriptors be ...
Is your QSAR/QSPR descriptor real or trash?
(Wiley-blackwellMaldenEUA, 2010)
Fractal descriptors for discrimination of microscopy images of plant leaves
(Institute of Physics - IOPBristol, 2014)
This study proposes the application of fractal descriptors method to the discrimination of microscopy images of plant leaves. Fractal descriptors have demonstrated to be a powerful discriminative method in image analysis, ...
