Speckle reduction in echocardiography by temporal compounding and anisotropic diffusion filtering
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 ...
Reduction of blooming artifacts in cardiac CT images by blind deconvolution and anisotropic diffusion filtering
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 ...
Analysis of sEMG signals using discrete wavelet transform for muscle fatigue detection
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, ...
Fetal ECG extraction using independent component analysis by Jade approach
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 ...
