Ultra-low-power Wireless Camera Network Nodes: Design and Performance Analysis
A methodology for designing Wireless Camera Network nodes featuring long lifetime is presented. Wireless Camera Networks may nd widespread application in the elds of security, animal monitoring, elder care and many others. Unfortunately, their development is currently thwarted by the lack of nodes …

Recognition of 3D compressed images and its traffic monitoring applications
… large numbers of images sent over communication networks. For example, a high transmission load results when security cameras continuously transmit images. Operators are bored and fatigued from viewing cycled images on a few monitors. In this thesis, we present a smart camera network that reduces …

Creating cohesive video with the narrative-informed use of ubiquitous wearable and imaging sensor networks
… little or no regulation on the proliferation of camera technology and the increasing use of video for social communication, entertainment, and education, we have undoubtedly entered the age of ubiquitous media. A world permeated by connected video devices promises a more democratized approach to …

Privacy-Preserving Video Analytics
As video cameras have become pervasive in public settings and accurate computer vision has become commonplace, there has been increasing interest in collecting and processing data from these cameras at scale ("video analytics"). While these trends enable many useful applications (such as monitoring …
