《Speckle Noise Reduction in Ultrasound Images》是一个数字图像处理项目,旨在解决超声图像中存在的斑点噪声问题。斑点噪声是由于超声波在组织结构中多次反射而形成的,在图像中表现为颗粒状的噪点,降低了图像的质量和清晰度。 该项目的详细描述包括以下内容:首先,对超声图像中的斑点噪声进行深入分析和研究,探讨其形成...
Background The Noise Power Spectrum (NPS) is an effective tool for providing information on how the total variance of uniformity images is distributed in frequency space. The NPS is a tool which can widen the understanding of noise in ultrasound as noise in this imaging modality includes both ...

Ultrasound is a widely used medical tool for noninvasive diagnosis, but its images often contain speckle noise which can lower their resolution and contrast-to-noise ratio. This can make it more difficult to extract, recognize, and analyze features in the images, as well as impair the accuracy...

In this paper, we propose a patch-based low-rank approach for reducing the speckle noise in ultrasound images. After constructing the patch group of the ultrasound images by the block-matching scheme, we establish a variational model using the weighted nuclear norm as a regularizer for the ...
Ultrasound imaging is a very essential technique in medical diagnosis due to its being safe, economical and non-invasive nature. Despite its popularity, the US images, however, are corrupted with speckle noise, which reduces US images qualities, hampering image interpretation and processing stage. ...
Statistical properties of log-speckle noise in ICE(Intracardiac Echocardiographic) ultrasound images are analyzed after extraction by an elastic image registration method based on cubic B-spline.The image registration is achieved by minimizing a cost functional constructed by stochastic modeling of speckle ...
