Perceptual quality assessment plays a vital role in the visual communication systems owing
to the existence of quality degradations introduced in various stages of visual signal …

Image quality assessment (IQA) has been a topic of intense research over the last several
decades. With each year comes an increasing number of new IQA algorithms, extensions of …

This work presents a perceptual-based no-reference objective image sharpness/blurriness
metric by integrating the concept of just noticeable blur into a probability summation model …

This paper presents an algorithm designed to measure the local perceived sharpness in an
image. Our method utilizes both spectral and spatial properties of the image: For each block …

Sharpness is an important determinant in visual assessment of image quality. The human
visual system is able to effortlessly detect blur and evaluate sharpness of visual images, but …

In this letter, we present a simple, yet effective wavelet-based algorithm for estimating both
global and local image sharpness (FISH, Fast Image Sharpness). FISH operates by first …

In a typical image communication system, the visual signal presented to the end users may
undergo the steps of acquisition, compression and transmission which cause the artifacts of …

This letter proposes a simple and fast approach for no-reference image sharpness quality
assessment. In this proposal, we define the maximum local variation (MLV) of each pixel as …

This paper aims to summarize central findings from a literature review and technical survey
on unmanned aerial vehicle (UAV) techniques for bridge inspection and damage …

Laser-wakefield accelerators (LWFAs) are high acceleration-gradient plasma-based particle
accelerators capable of producing ultra-relativistic electron beams. Within the strong …
