A Novel Cognitive Neuromorphic Polarimetric Dynamic Vision System (pDVS) with Enhanced Discrimination and Temporal Contrast

In this preliminary study, a new cognitive vision architecture of a Polarimetric Dynamic Vision Sensor (pDVS), is presented. The system consists of a neuromorphic camera coupled to polarization filters; a spinning wheel, namely, a light modulating wheel, operating at different speeds, is placed in front a static object. The detector system performance against different modulating speeds, under unpolarized and polarized conditions, has been tested, data were acquired and then analyzed. The outcome of this study indicates that enhanced temporal contrast resolution can be achieved, while offering unique discrimination capabilities, depending upon the light polarization states.
