Super-resolution (SR) is the process of combining multiple aliased low-quality images to
produce a high-resolution high-quality image. Aside from registration and fusion of low …

Speckle-based phase-contrast X-ray imaging (SB-PCXI) can reconstruct high-resolution
images of weakly-attenuating materials that would otherwise be indistinguishable in …

Purpose: We investigate how an intrinsic speckle tracking approach to speckle-based x-ray
imaging is used to extract an object's effective dark-field (DF) signal, which is capable of …

The focus of this paper is the study of modern non-blind image deconvolution methods and
their application to practical tasks. The aim of the study is to determine the current state-of …

Rendering three-dimensional information of a scene from optical measurements is very
important for a wide variety of applications. However, computer vision advancements have …

This paper presents a new approach for image segmentation by applying Pillar-Kmeans
algorithm. This segmentation process includes a new mechanism for clustering the elements …

We investigate the utility of plenoptic data for extracting information from a scene where the
light from objects in the scene is viewable only after scattering from a surface such as a wall …

Speckle-based phase-contrast X-ray imaging (SB-PCXI) can reconstruct high-resolution
images of weakly-attenuating materials that would otherwise be indistinguishable in …

Diffractive achromats (DAs) combined with image processing algorithms offer a promising
lens solution for high-performance ultra-thin imagers. However, the design of large-aperture …

In this paper, at first, a color image of a car is taken. Then the image is transformed into a
grayscale image. After that, the motion blurring effect is applied to that image according to …
