Region growing segmentation of ultrasound images using gradients and local statistics
(SPIE, 2017)
This paper describes a region growing segmentation algorithm for medical ultrasound images. The algorithm starts with anisotropic diffusion filtering to reduce speckle noise without blurring the edges. Then, region growing ...
Selection of a Stopping Criterion for Anisotropic Diffusion Filtering in Ultrasound Images
(Institute of Electrical and Electronics Engineers Inc., 2019)
Ultrasound imaging is a safe and cost-effective diagnostic tool, but the quality of the images is affected by speckle noise and artifacts. Anisotropic diffusion filters can be used to reduce noise and preserve the edges ...
A machine learning model for emotion recognition from physiological signals
(Elsevier Ltd, 2020)
Emotions are affective states related to physiological responses. This study proposes a model for recognition of three emotions: amusement, sadness, and neutral from physiological signals with the purpose of developing a ...
Acquisition and Analysis of Cognitive Evoked Potentials using an Emotiv Headset for ADHD Evaluation in Children
(Institute of Electrical and Electronics Engineers Inc., 2019)
Attention-deficit/hyperactivity disorder (ADHD) is a neurological condition that affects the quality of life of the patients. It can be diagnosed using a combination of psychological tests. In addition to that, the brain ...
Instrumented insole for plantar pressure measurement in sports
(Springer Verlag, 2018)
Novel technological aids have been developed to evaluate sport performance. Among these tools there are wearable sensors that monitor physical and physiological variables during the execution of exercises. This paper ...
Estimation of PQ distance dispersion for atrial fibrillation detection
(2021-05-03)
Background and objective: Atrial fibrillation (AF) is the most common cardiac arrhythmia in the world. It is
associated with significantly increased morbidity and mortality. Diagnosis of the disease can be based on
the ...
Vehicle speed estimation using audio features and neural networks
(Institute of Electrical and Electronics Engineers Inc., 2017)
Many car accidents that result in pedestrian deaths or serious injuries are due to their inattention when crossing the street. Pedestrians often get distracted using mobile phones or music players, what prevents them to ...
Analysis and classification of lung tissue in ultrasound images for pneumonia detection
(2020-01-03)
Pneumonia is an infection of the lungs caused by virus, bacteria or fungi. It affects mainly children under five and can be life-threatening. Diagnosis of pneumonia is usually performed using imaging techniques such as ...
Three-dimensional multimodal medical imaging system based on freehand ultrasound and structured light
(2021-05-21)
We propose a three-dimensional (3D) multimodal medical imaging system that combines freehand ultrasound and structured light 3D reconstruction in a single coordinate system without requiring registration. To the best of ...
Texture Analysis of Ultrasound Images for Pneumonia Detection in Pediatric Patients
(Institute of Electrical and Electronics Engineers Inc., 2019)
Pneumonia is a condition that can be life-threatening and affects a high number of children around the world. Lung ultrasound can be used for the diagnosis of pneumonia, but requires high experience. This paper presents ...
