Abstract
Dynamic Vision Sensors are innovative bio-inspired devices able to asynchronously detect pixel-wise brightness changes called “events”. The result is a stream of data encoding time, pixel location and sign of the captured intensity changes. Their novel data acquisition method provides significant advantages over conventional sensors, particularly in low-light and high-speed motion conditions. Indeed, their high pixel bandwidth reduces motion blur, a phenomenon which arises from their rapid and involuntary movements caused by the user, and their wide dynamic range makes them an attractive alternative to traditional cameras in challenging robotics and computer vision scenarios. Moreover, the low latency and low power consumption of these novel sensors enable their use in several new real-world applications, especially related to the field of wearable devices.
The aforementioned peculiarities make them ideal for addressing well-known issues associated with the usage of wearable devices, such as continuous visual stimuli and background clutter
