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 ...
Nuclear density analysis in microscopic images for the characterization of retinal geographic atrophy
Age-related macular degeneration (AMD) is the leading cause of irreversible blindness in industrialized countries. It is estimated that AMD affects at least 1 in 10 Hispanics. Previous reports have shown that AMD has ...
Segmentation and motion estimation applied to fetal heart analysis using a multi-texture active appearance model and an optical flow approach
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, ...
Image analysis applied to a freeze-concentration water purification system
(IMEKO-International Measurement Federation Secretariat, 2018-02)
Freeze concentration is a promising water purification technology, specially due to the low levels of energy consumption when compared with other processes such as evaporation. Nevertheless, its development is still at ...
Non-contact breathing rate monitoring system using a magnification technique and convolutional networks
In this paper, we present a new non-contact strategy to estimate the breathing rate based on the Eulerian motion video magnification technique and a system based on a Convolutional Neural Network (CNN). After the magnification ...
Hybrid methods to quantify ice front movement during freeze-concentration process
(Institute of Electrical and Electronics Engineers Inc., 2019)
Freeze concentration is an emerging separation method that can be implemented as part of a water purification system, however, its development is still at pilot plant scale. One of the useful parameters for design and ...
