A Low Power Vision Sensor for Sustainable Surveillance Activities: the FBK activity in the European Project FORENSOR

The massive diffusion and demand of technological devices supporting many human activities pose new challenges about energy consumption. The new trend of green technology is to promote more sustainable systems, capable to reduce power waste while keeping high performance levels. Here we describe a low-power vision sensor developed under an European H2020 project as a key node of an energy efficient surveillance system to be used by Law Enforcement Agencies (LEAs) to fight crimes. Such a sensor embeds an efficient motion detection algorithm based on dynamic background subtraction and running in real time with low power consumption. Its architecture, the image processing operations integrated on-chip, together with the low-power consumption, make the sensor a promising tool for LEAs investigative activities, as well as for many other surveillance and monitoring tasks, which are useful in modern smart environments.
