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 ... -
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 ... -
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 ...
