《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...
Speckle noise removal in ultrasound images is a challenging task due to the inherent speckle pattern caused by scattering of ultrasound waves. The first-order total variation (TV) and second-order TV are powerful tools that can be employed for this purpose. First-order TV is based on 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. ...

The removal of speckle noise in ultrasound images poses a major challenge in medical image analysis. Jubairahmed, et al. [96] discovered that conventional anisotropic diffusion could cause the loss of contour information in ultrasound images. They suggested employing contourlet transform to decompose ...

Ultrasound is a low-cost,non-invasive and real-time imaging modality that has proved popular for many medical applications.Unfortunately,the acquired ultrasound images are often corrupted by speckle noise from scatterers smaller than ultrasound beam wavelength.The signal-dependent speckle noise makes visua...
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 ...
