Enhancing Underwater Images via Color Correction and Multiscale Fusion
Applied Sciences, 2023 Color distortion, low contrast, and blurry details are the main features of underwater images, which can have adverse effects on their quality. To address these issues, a novel enhancement method based on color correction and multiscale fusion is ...

CONTRAST ENHANCEMENT OF SCANNING ELECTRON MICROSCOPY IMAGES USING A NONCOMPLEX MULTIPHASE ALGORITHM [PDF]
Applied Computer Science, 2022 Microscopic technology has recently flourished, allowing unparalleled viewing of microscopic elements invisible to the normal eye. Still, the existence of unavoidable constraints led on many occasions to have low contrast scanning electron ...

Preventing Over-Enhancement Using Modified ICSO Algorithm
IEEE Access, 2023 This paper proposes an Image Contrast Enhancement (ICE) method based on using an Improved Chicken Swarm Optimization (ICSO) algorithm to enhance images while at the same time preventing over-enhancement.

Effect of delayed acquisition times on Gadolinium-enhanced MRI of the presumably normal canine brain [PDF]
, 2011 A delay in imaging following intravenous contrast medium administration has been recommended to reduce misdiagnoses. However, the normal variation of contrast enhancement in dogs following a delay has not been characterized.

BioMed Research International, 2015 The recent decade has witnessed the great improvement of contrast-enhanced ultrasound (CEUS) and its extensive use in clinical practice, which is undoubtedly the major breakthrough in the field of diagnostic ultrasound in recent years. The concept of CEUS can be looked back to 60s in the last century, whereas only in 2000s CEUS regained increasing ...

Ramp Distribution-Based Contrast Enhancement Techniques and Over-Contrast Measure
IEEE Access, 2019 Our approach to contrast enhancement (CE) of images is based on natural scene statistics (NSS). We show, in this paper, that the average intensity distribution of natural images can be linearly approximated to the ramp distribution in an ordered ...

Heralded phase-contrast imaging using an orbital angular momentum phase-filter [PDF]
, 2016 We utilise the position and orbital angular momentum (OAM) correlations between the signal and idler photons generated in the down-conversion process to obtain ghost images of a phase object.
