American Journal of Orthodontics and Dentofacial Orthopedics, 2000
Although most orthodontists can rely on their orthodontic image software, those who have the need to go beyond just the monitor display of the images will need to get behind the scenes. Understanding a little of what makes up digital images and how to manipulate the variables will enable them to get optimum image quality as well as conserve on time ...

Clinics in Laboratory Medicine, 2012
Advances in computing speed and power have made a pure digital work flow for pathology. New technologies such as whole slide imaging (WSI), multispectral image analysis, and algorithmic image searching seem poised to fundamentally change the way in which pathology is practiced.

A watermark for digital images
Proceedings of 3rd IEEE International Conference on Image Processing, 2002The growth of networked multimedia systems has magnified the need for image copyright protection. One approach used to address this problem is to add an invisible structure to an image that can be used to seal or mark it. These structures are known as digital watermarks. We describe two techniques for the invisible marking of images.

IBM Journal of Research and Development, 1982
Most printers and some display devices are bilevel (black or white) and therefore not capable of reproducing continuous tone pictures. Digital halftoning algorithms transform digital gray scale images into bilevel ones which give the appearance of containing various shades of gray.

The British Journal of Radiology, 2005
There has been an increase in the use of digital imaging in recent years and radiologists have almost universally accepted the use of computers in their day-to-day work. Completely filmless radiology departments, with all reporting being done on visual display terminals and picture archiving and communications systems (PACS) around the department, are ...

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1987
Nielsen et al. recently addressed the problem of determining the optimal discretization grid and quantization depth when a given bivariate function f(x, y) has to be described with a predetermined number of bits. This was done under the assumption that the function value range and mean "fluctuation rates" in the x and y direction are given, and that ...

IEEE Signal Processing Magazine, 2009
The article explains how photo-response nonuniformity (PRNU) of imaging sensors can be used for a variety of important digital forensic tasks, such as device identification, device linking, recovery of processing history, and detection of digital forgeries.
