Iteratively Reweighted Blind Deconvolution With Adaptive Regularization Parameter Estimation

IEEE Access, 2017
In many realistic image processing applications, the acquired images often suffer from mixed noises and blurring, which greatly degrade the image quality.

Impact of partial volume correction on radiomics reproducibility in theranostic SPECT/CT imaging

Medical Physics, Volume 53, Issue 4, April 2026.
Abstract Background: Radiomics has shown potential for quantitative characterization of tumors in molecular imaging; however, its clinical translation in theranostic 177Lu SPECT/CT remains limited due to poor robustness of extracted features to reconstruction variability and partial volume effects.

Role of Succinate Dehydrogenase in Age‐Related Th17 Inflammation

Aging Cell, Volume 25, Issue 4, April 2026.
Age‐induced mitoSTAT3‐dependent upregulation of mitochondrial complex II; succinate dehydrogenase (SDH), in CD4+ T cells promotes an imbalance in the levels of metabolites succinate and fumarate, characterized by lower succinate and higher fumarate. Changes in the metabolites alter mitochondrial structure and function and promote HIF1α to induce the ...

Tumor‐Associated Macrophage‐Derived CXCL1 Promotes Endometrial Cancer Progression Through the CXCR2/NF‐κB Pathway

Cancer Science, Volume 117, Issue 4, Page 1026-1042, April 2026.
CXCL1 secreted by M2 macrophages induced EMT of EC cells through the CXCR2/NF‐κB pathway; CXCR2 expression was predominantly observed in the epithelial compartment, whereas CXCL1 expression was primarily localized in the stromal region; Neutralization of M2 macrophage‐secreted CXCL1 and inhibiting the NF‐κB pathway can inhibit EC progression in vivo ...

Rapid, Robust, and Reliable Blind Deconvolution via Nonconvex Optimization

, 2016
We study the question of reconstructing two signals $f$ and $g$ from their convolution $y = f\ast g$. This problem, known as {\em blind deconvolution}, pervades many areas of science and technology, including astronomy, medical imaging, optics, and ...

Richardson–Lucy Iterative Blind Deconvolution with Gaussian Total Variation Constraints for Space Extended Object Images

Photonics
In ground-based astronomical observations or artificial space target detections, images obtained from a ground-based telescope are severely distorted due to atmospheric turbulence. The distortion can be partially compensated by employing adaptive optics (

A mixed single image motion deblur method

Dianzi Jishu Yingyong, 2019
The blind recovery of images is a difficult problem in the field of digital image processing. Researching the restoration of motion blurred images，a hybrid single image motion deblur method is proposed.

A unified approach to solve ill-posed inverse problems in econometrics [PDF]

We consider the general issue of estimating a nonparametric function x from the inverse problem r = Tx given estimates of the function r and of the linear transform T. Two typical examples include the estimation of a probability density function fromdata
