Intravenous Arteriography Using Digital Subtraction Techniques

JAMA: The Journal of the American Medical Association, 1982
The application of digital computers to electronic x-ray imaging devices has rejuvenated interest in the field of intravenous arteriography. By utilizing computer image subtraction techniques, digital roentgenographic systems based on fluoroscopy or computed tomography (scanned projection radiography) provide significantly improved vascular imaging ...

An Efficient Region-Based Background Subtraction Technique

2008 Canadian Conference on Computer and Robot Vision, 2008
This paper proposes an efficient region-based background subtraction technique using static camera for motion detection in various monitoring applications. Color histograms, texture information, and successive division of candidate rectangular image regions are utilized to model the background and detect the motion.
