ENERGY-EFFICIENT LIGHTWEIGHT ALGORITHMS FOR EMBEDDED SMART CAMERAS: DESIGN, IMPLEMENTATION AND PERFORMANCE ANALYSIS
<p>An embedded smart camera is a stand-alone unit that not only captures images, but also includes a processor, memory and communication interface. Battery-powered, embedded smart cameras introduce many additional challenges since they have very limited resources, such as energy, processing power …

Recognition of 3D compressed images and its traffic monitoring applications
… 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 transmission load and provides operators with relevant images. A …

A Two-Phase Buck Converter with Optimum Phase Selection for Low Power Applications
Power consumption of smart cameras varies significantly between sleep mode and active mode, and a smart camera operates in sleep mode for 80 — 90% of time for typical use. To prolong the battery life of smart cameras, it is essential to increase the power converter efficiency for light load, while …

Information selection and fusion in vision systems
… high-bandwidth video streams between cameras should be avoided. Fortunately, recently designed 'smart cameras', which have on-board processing and communication hardware, allow distributing the required image processing over the cameras. This permits compactly representing useful …

GICEDCAM: A Geospatial Internet of Things Framework for Complex Event Detection in Camera Streams
… The second study develops an Internet of Smart Cameras (IoSC) architecture that uses edge–cloud collaboration and overlapping camera views to compensate for missed detections. By integrating simple events detected from multiple viewpoints, the IoSC framework significantly reduces false …

A Constant ON-Time 3-Level Buck Converter for Low Power Applications
Smart cameras operate mostly in sleep mode, which is light load for power supplies. Typical buck converter applications have low efficiency under the light load condition, primarily from their power stage and control being optimized for heavy load. The battery life of a smart camera can be extended …
