Freezing front velocity estimation using image processing techniques
(Elsevier B.V., 2020-02)
Freeze concentration is a promising water purification technology due to its low energy consumption when compared with traditional procedures such as evaporation. Crystal growth velocity is an important parameter for the ...
A non-contact heart rate estimation method using video magnification and neural networks
(Institute of Electrical and Electronics Engineers Inc., 2020-06)
Heart rate (HR) monitoring is a significant task in many medical, sports and aged care in assisted living applications, among other disciplines. In the literature, several works have reported effectiveness in addressing ...
Video motion magnification for monitoring of vital signals using a perceptual model
(SPIESociety of Photo-optical Instrumentation Engineers, 2017)
In this paper we present an Eulerian motion magnification technique using a spatial decomposition based on the Steered Hermite Transform (SHT) which is inspired in the Human Vision System (HVS). We test our method in one ...
Heart rate estimation using Hermite transform video magnification and deep learning
(Institute of Electrical and Electronics Engineers Inc., 2018)
Monitoring of heart rate can be used in many medical and sports applications. Lack of portability and connection problems make traditional monitoring methods difficult to use outside of clinical environments. The computer ...
Distance estimation using a bio-inspired optical flow atrategy applied to neuro-robotics
(Institute of Electrical and Electronics Engineers Inc., 2018)
Movement detection and characterization of a 3D scene are relevant tasks in vision systems and particularly in robotic applications controlled by visual features. One of the challenges to characterize a 3D scene in navigation ...
Non-contact breathing rate monitoring system based on a Hermite video magnification technique
(SPIE, 2018)
In this paper we present a new non-contact strategy to estimate the breathing rate based on the Eulerian motion magnification technique and a system based on di€erent images processing steps. After the magnification ...
Segmentation and motion estimation applied to fetal heart analysis using a multi-texture active appearance model and an optical flow approach
(SPIE, 2018)
In this work we present a combination of segmentation and motion estimation methods applied to left ventricle evaluation in fetal echocardiographic images which are used for prenatal diagnosis. In our proposed scheme, ...
Thoughts and emotion assimilation and detonation through VR for people with ASD
(SPIE, 2018)
This study proposes a new tool based on Virtual Reality (VR) as a complement in the treatment of people diagnosed with Autism Spectrum Disorder (ASD). VR tools have been stablished in last years as a new option in learning ...
3D optical flow estimation in cardiac CT images using the hermite transform
(SPIESociety of Photo-optical Instrumentation Engineers, 2017)
Heart diseases are one of the most important causes of death in the Western world. It is, then, important to implement algorithms to aid the specialist in analyzing the heart motion. We propose a new strategy to estimate ...
An intelligent human fall detection system using a vision-based strategy
(Institute of Electrical and Electronics Engineers Inc., 2019)
Elderly people is increasing dramatically during the current years, and it is expected that this population reaches 2.1 billion of individuals by 2050. In this regard, new care strategies are required. Assisted living ...
