On the compensation of uneven illumination in retinal images for restoration by means of blind deconvolution
(Institute of Electrical and Electronics Engineers Inc., 2016)
Retinal eye fundus images are used for diagnostic purposes, but despite controlled conditions in acquisition they often suffer from uneven illumination and blur. In this work, we propose the use of multi-channel blind ...
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 ...

Advances in the field of biomedical engineering have allowed the development of biometric devices to evaluate sport performance. This article describes the design and construction of a wearable electrogoniometer to monitor ...
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 ...
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 ...
