How to make a small phone camera shoot like a big DSLR: creating and fusing multi-modal exposure series

The present work aims at improving the image quality of low-cost cameras based on multiple exposures, machine learning, and a perceptual quality measure. The particular implementation consists of two cameras, one being a high-quality DSLR, the other part of a cell phone. The cameras are connected via USB. Since the system is designed to take many exposures of the same scene, a stable mechanical...

SecureTime: Secure Multicast Time Synchronization

Due to the increasing dependency of critical infrastructure on synchronized clocks, network time synchronization protocols have become an attractive target for attackers. We identify data origin authentication as the key security objective and suggest to employ recently proposed high-performance digital signature schemes (Ed25519 and MQQ-SIG)) as foundation of a novel set of security measures t...

The Proficiency Testing Program of the American College of Nuclear Physicians

One of the ways the nuclear medicine community meets the challenge of managed health care is through participation in the Proficiency Testing Program (PTP) under the guidance of the American College of Nuclear Physicians (ACNP). This self-assessment program offers education opportunities to technologists and physicians, evaluates scintillation camera performance and offers techniques to optimiz...

Comparametric Transforms for Transmitting Eye Tap Video with Picture Transfer Protocol (PTP)

Wireless transfer of images from a digital camera to the Internet via a standard GSM mobile phone

In this paper we describe an infrastructure based on an existing, commercially available, GSM mobile phone for achieving .connectivity between digital cameras and an Internet Website. Pictures are loaded from a standard digital camera, or compact flash card, by an embedded appliance, which establishes the Internet connection and controls the transfer of pictures from the camera to a remote webs...
