Guest Editorial: Ubiquitous Multimedia Systems and Applications

Abstract

The technologies of computing and communications have undergone a series of evolutionary innovation over the past decades and improved the quality of human life significantly. Ubiquitous computing and communications is a revolutionary paradigm that aims to provide pervasive and reliable computing solutions and communication services anytime and anywhere. This emerging technology is built upon the rapid research and development advances in a wide range of key areas including wireless and sensor networks, mobile and distributed computing, embedded systems, agent technologies, autonomic communication and information security. Ubiquitous computing and communications has drawn significant interests from both academia and industry and continues to attract tremendous research efforts due to its promising new business opportunity in information technology and engineering. This special issue is devoted to papers addressing research challenges and advances towards the design, implementation and evaluation of ubiquitous multimedia computing and communications technologies, systems and applications. This special issue contains six papers, which are briefly introduced as follows. Exposure fusion is an efficient way for producing high-quality images for common low dynamic range (LDR) output devices from multiple differently exposed LDR images of the same scene, which has significant potential to be applied in the ubiquitous multimedia area. In the paper entitled BA Novel Method for Fusion of Differently Exposed Images Based on Spatial Distribution of Intensity for Ubiquitous Multimedia^ (10.1007/s11042-013-1660-0), Multimed Tools Appl (2015) 74:2743–2744 DOI 10.1007/s11042-015-2458-z
