We present a pixel-specific, measurement-driven correction that effectively reduces errors in
detector response that give rise to the ring artifacts commonly seen in X-ray computed …

In this article, we introduce a new ring artifacts reduction procedure that combines several
ideas from existing methods into one complex and robust approach with a goal to overcome …

Ring artifacts pose a major barrier to obtaining precise reconstruction in computed
tomography (CT). The presence of ring artifacts complicates the use of automatic means of …

In computed tomography (CT) reconstruction, ring artifacts emerge from incorrectly
normalized or defective detector elements. Correction algorithms often introduce blur or do …

A cone-beam CT imaging system is designed to image internal structures of complex
objects, and four analytical-based algorithms are applied on projected domain sinograms to …

摘要同步辐射光源具有高斯分布特性, 能使生物样品重建图像呈灰度分布不均匀和对比度低的
特点, 同时重建图像受背景噪声影响, 进而造成重建生物样品的一些细节特征难以被观察和分析 …

CT reconstruction from incomplete projection data is one of the key researches of X-ray CT
imaging. The projection data acquired by few-view and limited-angle sampling are …

为解决多谱段降质图像增强问题, 提出了一种基于光照-反射成像模型和形态学操作的多谱段
图像增强算法. 首先对图像饱和度使用自适应非线性拉伸函数进行拉伸, 使增强后的图像色彩 …

Ring artifacts in X-ray micro-CT images are one of the primary causes of concern in their
accurate visual interpretation and quantitative analysis. The geometry of X-ray micro-CT …

A multiple-image encryption method based on two-step phase-shifting interferometry (PSI)
and spatial multiplexing of a smooth compressed signal is proposed. In the encoding and …
