Neonatal Cranial Ultrasonography
It provides important information on brain maturation in the (preterm) neonate and enables the detection of frequently occurring brain anomalies in both preterm and full term neonates. Furthermore, it can be repeated as often as is necessary. In this edition of Neonatal Cranial Ultrasonography, the focus is on the basics of the technique, from patient preparation through to screening strategies and the classification of abnormalities. Many new ultrasound images have been included to reflect the improvements in image quality since the first edition. Essential information is provided about both the procedure itself and the normal ultrasound anatomy. Standard technique using the anterior fontanelle as the acoustic window is described and illustrated, but emphasis is also placed on the value of supplementary acoustic windows.
Improving image quality in visual cryptography
This book comprehensively covers the important efforts in improving the quality of images in visual cryptography (VC), with a focus on cases with gray scale images. It not only covers schemes in traditional VC and extended VC for binary secret images, but also the latest development in the analysis-by-synthesis approach.

Electronic Imaging in Astronomy : Detectors and Instrumentation
The second edition of Electronic Imaging in Astronomy: Detectors and Instrumentation describes the remarkable developments that have taken place in astronomical detectors and instrumentation in recent years – from the invention of the charge-coupled device (CCD) in 1970 to the current era of very large telescopes, such as the Keck 10-meter telescopes in Hawaii with their laser guide-star adaptive optics which rival the image quality of the Hubble Space Telescope. Authored by one of the world’s foremost experts on the design and development of electronic imaging systems for astronomy, this book has been written on several levels to appeal to a broad readership. Mathematical expositions are designed to encourage a wider audience, especially among the growing community of amateur astronomers with small telescopes with CCD cameras.
Echocardiographic Anatomy in the Fetus
With recent advances in ultrasound systems, storing multiple digital frames and clips with superb image quality has become a reality. These advances have brought innovative applications into the clinical field and can be integrated into powerful multimedia presentations for teaching purposes.

Advances in image enhancement
In the era of the internet of things, images have played important roles in human–computer interactions, and with the arrival of big data technology, people have higher requirements regarding image quality, especially for images collected in dark light. This can be addressed through the development of camera hardware quality, i.e., the resolution and exposure time of cameras, which may require high computational costs. As an alternative, image enhancement techniques can exact salient features to improve the quality of captured images according to the differences in diverse features, although they suffer from some challenges, i.e., a low contrast, artifacts, and overexposure, thus making it decidedly necessary to determine how to use advanced image enhancement techniques.
