JPEG is the most widely used lossy image compression standard. When using JPEG with
high compression ratios, visual artifacts cannot be avoided. These artifacts not only degrade …

Computed tomography (CT) imaging technology has been widely used to assist medical
diagnosis in recent years. However, noise during the process of imaging, and data …

The most widely used video encoders share a common hybrid coding framework that
includes block-based motion estimation/compensation and block-based transform coding …

X-ray computed tomography (CT) enables nondestructive evaluation and dimensional
metrology using the reconstructed volumes of measured objects. Although the abundant …

The problem of recovering an image of interest from nonlinear measured data is
challenging. To address this nonlinear imaging inverse problem, we propose a novel Plug …

The frequency recognition algorithm for multiple exposures (FRAME) is a spatial frequency
multiplexing method that enables high-speed videography with high spatial resolution …

The defocusing phenomenon of an optical system is determined by the defocus convolution
kernel (DCK). However, the DCKs in the current defocusing theories fail to match the …

The goal of image enhancement methods is to improve image's quality. The efficacy of U‐
net is evident through its extensive utilization across various significant image modalities …

Image blurring refers to the degradation of an image wherein the image's overall sharpness
decreases. Image blurring is caused by several factors. Additionally, during the image …

当前去模糊方法只利用图像单一的稀疏特性作为先验信息, 忽略了伪边缘(如振铃瑕疵)
对模糊核估计的影响, 导致其去模糊性能不佳. 本文充分利用复杂结构图像的先验信息 …
