Applied Optics, 1988
A new technique, digital image velocimetry, is proposed for measurement of instantaneous velocity fields of time dependent flows. A time sequence of single-exposure images of seed particles are captured with a high speed camera, and the sampled images are then digitized on an image processor, enhanced, and superposed to construct a multiple-exposure ...

Journal of Thoracic Imaging, 1985
The development of effective methods for producing digital chest radiographs is essential if the totally digital radiology department of the future is to evolve. Digital radiography of the chest is now possible with a variety of techniques. The most promising approach currently in clinical use involves the use of large-area detectors composed of ...

Dental Clinics of North America, 2000
Electronic sensors in diagnostic radiology are gradually replacing radiographic film. The advantages of this new technology include a lower radiation dose to the patient, an almost instantaneous availability of images without the need for chemical film processing, and the possibility of image enhancement and computer-aided feature extraction.

Clinical Orthopaedics & Related Research, 2004
Increasingly orthopaedic departments are using digital radiology and imaging systems. We review the technical features of a digital radiology system for the orthopaedic surgeon. The pros and cons of digital and computed radiology are discussed. Hardware and software requirements for storage, retrieval, manipulation, and display of digital images are ...

Proceedings of the 11th annual conference on Computer graphics and interactive techniques, 1984
Most computer graphics pictures have been computed all at once, so that the rendering program takes care of all computations relating to the overlap of objects. There are several applications, however, where elements must be rendered separately, relying on compositing techniques for the anti-aliased accumulation of the full image.

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.

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 ...

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.
