Reduction of blooming artifacts in cardiac CT images by blind deconvolution and anisotropic diffusion filtering
(SPIE, 2015)
Even though CT is an imaging technique that offers high quality images, limitations on its spatial resolution cause blurring in small objects with high contrast. This phenomenon is known as blooming artifact and affects ...
EEG feature selection for ADHD detection in children
(2020-11-03)
Attention deficit and hyperactivity disorder (ADHD) is a medical condition that affects approximately 7% of children worldwide. The diagnosis of ADHD can be done using psychological tests and electroencephalography (EEG). ...
Deep learning architectures for the analysis and classification of brain tumors in MR images
(2020-11-03)
The need to make timely and accurate diagnoses of brain diseases has posed challenges to computer-aided diagnosis systems. In this field, advances in deep learning techniques play an important role, as they carry out ...
Analysis of sEMG signals using discrete wavelet transform for muscle fatigue detection
(SPIE, 2017)
The purpose of the present article is to characterize sEMG signals to determine muscular fatigue levels. To do this, the signal is decomposed using the discrete wavelet transform, which offers noise filtering features, ...
Speckle reduction in echocardiography by temporal compounding and anisotropic diffusion filtering
(SPIE, 2015)
Echocardiography is a medical imaging technique based on ultrasound signals that is used to evaluate heart anatomy and physiology. Echocardiographic images are affected by speckle, a type of multiplicative noise that ...
Fetal ECG extraction using independent component analysis by Jade approach
(SPIE, 2017)
Fetal ECG monitoring is a useful method to assess the fetus health and detect abnormal conditions. In this paper we propose an approach to extract fetal ECG from abdomen and chest signals using independent component analysis ...
Analysis and classification of lung and muscular tissues in ultrasound images using 2D wavelet transform and machine learning
(2020-11-03)
Ultrasound has been considered a safe and accurate alternative to radiography and computerized tomography to diagnose lung diseases such as pneumonia. However, speckle noise, artifacts or certain conditions can difficult ...
