《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...
UltrasoundUltrasound imaging is the most popular, non-invasive and inexpensive diagnostic tool in clinical imaging for treatment planning and therapy. Due to noise and artefacts present, pre-processing of these images is difficult which leads to poor image processing and analysis. In this paper, an...
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 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...
speckle noiseBackground: Ultrasound (US) imaging can be a convenient and reliable substitute for magnetic resonance imaging in the investigation or screening of articular cartilage injury. However, US images suffer from two main impediments, i.e., low contrast ratio and presence of speckle noise....
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. ...
Speckle noise is an inherent yet ineffectual residual artifact in medical ultrasound images, which significantly degrades quality and restricts accuracy in automatic diagnostic techniques. Speckle reduction is therefore an important step prior to the analysis and processing of the ultrasound images. A new...
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 ...
The application of the algorithm for image compression based on the inverse difference pyramid (IDP) permits together with considerable compression ratio to achieve suppression of the specific (speckle) noise in ultrasound medical images. The paper describes the principle of image decomposition and its ...
