Focal-plane sensing-processing: a power-efficient approach for the implementation of privacy-aware networked visual sensors [Article]
(MDPI, 2014)
The capture, processing and distribution of visual information is one of the major challenges for the paradigm of the Internet of Things. Privacy emerges as a fundamental barrier to overcome. The idea of networked image ...
A CMOS Digital SiPM With Focal-Plane Light-Spot Statistics for DOI Computation [Article]
(Institute of Electrical and Electronics Engineers, 2017)
Silicon photomultipliers can be used to infer the depth-of-interaction (DOI) in scintillator crystals. DOI can help to improve the quality of the positron emission tomography images affected by the parallax error. This ...
Early forest fire detection by vision-enabled wireless sensor networks [Article]
(CSIRO Publishing, 2012)
Wireless sensor networks constitute a powerful technology particularly suitable for environmental monitoring. With regard to wildfires, they enable low-cost fine-grained surveillance of hazardous locations like wildland-urban ...
A QVGA Vision Sensor with Multi-functional Pixels for Focal-Plane Programmable Obfuscation [Presentation]
(Institute of Electrical and Electronics Engineers, 2014)
Privacy awareness constitutes a critical aspect for smart camera networks. An ideal awless protection of sensitive information would boost their application scenarios. How- ever, it is still far from being achieved. Numerous ...
Demo: A Prototype Vision Sensor for Real-time Focal-plane Obfuscation through Tunable Pixelation [Presentation]
(Institute of Electrical and Electronics Engineers, 2014)
Privacy concerns are hindering the introduction of smart camera networks in prospective application scenarios like retail analytics, factory monitoring or elderly care. The idea of networked cameras pervasively collecting ...
Multi-resolution low-power Gaussian filtering by reconfigurable focal-plane binning [Presentation]
(The International Society for Optics and Photonics, 2011)
Gaussian filtering is a basic tool for image processing. Noise reduction, scale-space generation or edge detection are examples of tasks where different Gaussian filters can be successfully utilized. However, their ...
