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 …

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 …

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 goal of image enhancement methods is to improve image's quality. The efficacy of U‐

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 …

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

Image deblurring, which is an important branch of digital image processing, is one of the
difficulties in digital image processing. The main goal of image deblurring is to improve the …
