Event-based imaging velocimetry - An introduction

Abstract

The presentation provides an introduction to the concepts of event-based imaging (EBI), also known as dynamic vision sensing or neuromorphic imaging. EBI constitutes a pradigm shift in the field of imaging since it does not record typical frame-based image data. Rather, the EBI sensor provides an asynchronous stream of contrast-change events on the pixel level. In the present context the focus is to demonstrate the potentials of EBI in the field of flow visualization and measurement, in particular, particle tracking velocimetry and flow field reconstruction akin to the established particle image velocimetry technique (PIV).
