ENHANCING MULTISCALE FRACTAL DESCRIPTORS USING FUNCTIONAL DATA ANALYSIS
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2010)
This work presents a novel approach in order to increase the recognition power of Multiscale Fractal Dimension (MFD) techniques, when applied to image classification. The proposal uses Functional Data Analysis (FDA) with ...
Metrics of performance for discrete-time descriptor jump linear systems
(ElsevierAmsterdam, 2014-03)
Analytical tools to measure the performance of a control system described by a discrete-time descriptor jump linear system are given. Specifically, a closed-form expression for the steady-state output power as well as a ...
Fractal descriptors based on Fourier spectrum applied to texture analysis
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
This work proposes the development and study of a novel technique lot the generation of fractal descriptors used in texture analysis. The novel descriptors are obtained from a multiscale transform applied to the Fourier ...
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 ...
Handwritten feature descriptor methods applied to fruit classification
(2018-01-01)
Several works have presented distinct ways to compute feature descriptor from different applications and domains. A main issue in Computer Vision systems is how to choose the best descriptor for specific domains. Usually, ...
Ground and excited state similarity studies by means of Fukui and dual-descriptor matrices
(Elsevier Science, 2012-10)
This Letter reports a quantitative study of the similarity between the Fukui matrices corresponding to the ground state and those of the first excited state of a molecular system, as well as between the dual-descriptor ...
Combination of HSV and RGB histograms and MPEG-7 Descriptor: Preliminar Results and Future Work
(2012-12)
In this paper we present the partial results obtained
with a new approach to combine HSV and RGB histograms
and MPEG-7 CLD descriptor. The combination
was conducted using Borda Voting-Schemes in three
databases: Wang, ...
MathFeature: feature extraction package for DNA, RNA and protein sequences based on mathematical descriptors
(2022-01-17)
One of the main challenges in applying machine learning algorithms to biological sequence data is how to numerically represent a sequence in a numeric input vector. Feature extraction techniques capable of extracting ...
Robust state prediction for descriptor systems
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
This paper deals with the problem of state prediction for descriptor systems subject to bounded uncertainties. The problem is stated in terms of the optimization of an appropriate quadratic functional. This functional is ...
