We propose a quad-tree scheme for obtaining sub-pixel estimates of interframe motion in the frequency domain. Our scheme is based on phase correlation and uses motion compensated ...
Abstract— Wireless Wide Area Networks (WWANs) are becoming ubiquitous across most geographic regions, enabling simultaneous coverage from multiple providers. WWAN channels exhibi...

Abstract— We developed an automated environment to measure the memory access behavior of applications on high performance clusters. Code optimization for processor caches is cruc...
—This paper presents a compressed-domain fall incident detection scheme for intelligent home surveillance applications. For object extraction, global motion parameters are estima...
Recently, hackers has been developing fast propagating worms exploiting vulnerabilities that had just been disclosed by security experts. Those attacks particularly expose servers...
