A technique to quickly detect motion blur from mobile phone camera and its implementation on an iPhone 4S were presented. GPU was utilized to accelerate the implementation. Direction of motion relative to the image space was used in addition to the image itself to detect motion blur. The accuracy of detection was 75%, and computation took on average 0.73 seconds for 8MP image on an iPhone 4S. E...

according to abū al-barakāt baghdādī, time and place are a priori conditions of motion; moreover, against the peripatetic philosophers, for whom time is the measure of motion, he holds that time is the measure of existence. nevertheless, he believes that we can define motion on the basis of our intuitive non-scientific concept of time and, by so doing, we can resolve the apparent circularity of...

background: in radiation treatment of moving targets located in thorax region of patient body, the delivered dose does not match with the planned treatment, resulting in some over and under dosage in the tumor volume, as a function of motion magnitude and frequency. several efforts have been done to investigate the target motion effects on dose distribution in the target and surrounding normal ...

with the arrival of increasingly higher resolution pet systems, small amounts of motion can cause significant blurring in the images, compared to the intrinsic resolutions of the scanners. in this work, we have reviewed advanced correction methods for the three cases of (i) unwanted patient motion, as well as motions due to (ii) cardiac and (iii) respiratory cycles. for the first type of motion...

studied and discussed at the enterprise level. However, global challenges remain in the twentyfirst century at the macroand strategic-management levels, one of the foremost of those challenges being how to strategically manage sustainable development and a green economy. In China, the acceleration of the economic development transformation mode has marked a profound change in socioeconomic refo...

Speed management has been an extensive focus of traffic safety research dating back to the 1960’s. Research has generally shown crash risk to increase as the average speed of traffic increases and as the standard deviation of travel speeds increases within a traffic stream. However, research as to the effects of speed limits has been somewhat inconclusive. This study investigates how speed limi...

Representing and processing semantic information regarding individual documents is desirable but not sufficient. To improve the efficiency and reusability of users’ work with Web-based information management systems, it is essential to handle document collections. We describe techniques for representing semantics both of collections and of information management services that operate upon them....

Tumors in thoracic and upper abdomen regions such as lungs, liver, pancreas, esophagus, and breast move due to respiration. Respiration-induced motion introduces uncertainties in radiotherapy treatments of these sites and is regarded as a significant bottleneck in achieving highly conformal dose distributions. Recent developments in radiation therapy have resulted in (i) motion-encompassing, (i...

The future success of Navy-Marine Corps operations in the extended littoral battlespace will depend critically on organic mine countermeasure capabilities. A battlegroup commander will require tools to rapidly detect, classify, and identify mines and form a tactical picture of mined areas, so a decision can be made to punch through the minefield, avoid it, or wait for dedicated mine countermeas...
