The power of imaging

Abstract: Imaging is rapidly gaining usage across businesses and institutions because of its special technology which allows huge numbers of words, pictures and other illustrations to be reduced to a tiny fraction of the space needed to store originals The emergence of imaging is being seen in numerous and varied applications around the world Some of them chronicled in the article are: — Images on billions of pieces of paper are being transformed to image systems at the US National Archives There, documents are stored in less than 05% of the space required on paper — Businesses in the United States have an estimated 324 billion paper documents stored — 95% of business information is stored on paper Corporations are seeking ways to apply imaging systems to this problem The Association for Information and Image Management (AIIM) estimates that the market for imaging systems will be $68 billion by 1993 — Imaging technology is established to enable users to use a kind of electronic shorthand to reduce such illustrations as engineering drawings from 8 Mb to 300 kb — thus enhancing ability to transmit and share such drawings at remote sites — Banks have a massive need to use imaging systems to process checks, now a time‐consuming and expensive task Since all of this work is now done by humans, use of imaging eliminates the repetitive and boring aspect of the work — Electronic filing systems can retrieve file folders in a matter of seconds Ordinary file folders require manual handling and misfiling is a problem Insurance claims processing requires massive amounts of paperwork and storage With imaging systems, these claims can be electronically processed and available to remote users — Companies such as American Express, American Airlines and American Hospital Corporation all are using imaging systems to gain competitive advantage in dealing with their enormous loads of paperwork

Snapshot differential imaging method based on flight time sensor

Abstract: The invention provides a snapshot differential imaging method based on a flight time sensor. The main content of the method includes: a differential imaging rule, prototype design of a differential imaging instrument, global segmentation based on polarity, and a method of recovering two images based on a single differential image. The process includes: capturing a plurality of images in sequence, performing differential calculation on the images, and processing the images together. The method causes the generation of artifacts during recording of a dynamic scene, therefore, the snapshot differential imaging method which is realized in sensor hardware of a flight time camera is designed. According to the snapshot differential imaging technology proposed by the method, direct global illumination segmentation, temporal-spatial image gradient direct imaging, and direct depth edge imaging all achieve good timeliness and accuracy.

Research on Java Imaging Technology and Its Programming Framework

Abstract: With the rapid increase on requirement of the cross-platform distributed imaging technology, and the common, stable imaging lib, SUN provided a complete solution based Java platform technology. This paper analyzed the evolution of java imaging technology such as Java AWT, Java 2D and Java Advanced Imaging. Especially, it details the image operators, the core classes and the programming framework of Java Advanced Imaging. At last, the paper gave out two imaging examples included the programming codes and the result images, which can be used in project.

Utilizing Light-field Imaging Technology in Neurosurgery.

Abstract: Traditional still cameras can only focus on a single plane for each image while rendering everything outside of that plane out of focus. However, new light-field imaging technology makes it possible to adjust the focus plane after an image has already been captured. This technology allows the viewer to interactively explore an image with objects and anatomy at varying depths and clearly focus on any feature of interest by selecting that location during post-capture viewing. These images with adjustable focus can serve as valuable educational tools for neurosurgical residents. We explore the utility of light-field cameras and review their strengths and limitations compared to other conventional types of imaging. The strength of light-field images is the adjustable focus, as opposed to the fixed-focus of traditional photography and video. A light-field image also is interactive by nature, as it requires the viewer to select the plane of focus and helps with visualizing the three-dimensional anatomy of an image. Limitations include the relatively low resolution of light-field images compared to traditional photography and video. Although light-field imaging is still in its infancy, there are several potential uses for the technology to complement traditional still photography and videography in neurosurgical education.

Emerging imaging techniques after cardiac transplantation.

Abstract: Improvements in survival after cardiac transplantation have in part been driven by improved graft surveillance. Graft surveillance relies mainly on 3 techniques: coronary angiography, endomyocardial biopsy and echocardiography. Developments in invasive and non-invasive imaging technology have revolutionized assessment of the heart in both health and disease, offering new insights into tissue composition and myocardial metabolism. Herein we aim to review the strengths and weaknesses of these techniques, and summarize the evidence in the following 5 fields of cardiac imaging after transplantation: cardiovascular magnetic resonance; computed tomography; positron emission tomography; single-photon emission computed tomography; and optical coherence tomography and molecular imaging techniques.
