Cardiac Pulse Modeling Using a Modified van der Pol Oscillator and Genetic Algorithms
Fabián M. Lopez-Chamorro,Andrés F. Arciniegas-Mejia,David Esteban Imbajoa-Ruiz,Paul D. Rosero-Montalvo,Pedro García,Andrés Eduardo Castro-Ospina,Antonio Acosta,Diego Hernán Peluffo-Ordóñez +7 more
TL;DR: An approach for modeling cardiac pulses from electrocardiographic signals (ECG) using a modified van der Pol oscillator model (mvP) which, under a proper configuration, is capable of describing action potentials, and can be adapted for modeling a normal cardiac pulse.
Book ChapterDOI
Spectral Clustering Using Compactly Supported Graph Building
TL;DR: This work introduces a new graph building strategy based on a compactly supported kernel technique that makes relevant pair-wise sample relationships by finding a sparse kernel matrix that codes the main sample connections.
Book ChapterDOI
Fingertips Segmentation of Thermal Images and Its Potential Use in Hand Thermoregulation Analysis
Andrés Eduardo Castro-Ospina,A. M. Correa-Mira,Israel David Herrera-Granda,Diego Hernán Peluffo-Ordóñez,H. A. Fandiño-Toro +4 more
TL;DR: This work proposes an algorithm for fingertip segmentation in thermal images of the hand by using a supervised index, and the results are compared against segmentations provided by humans.
