On event-based optical flow detection
Event-based sensing, i.e., the asynchronous detection of luminance changes, promises low-energy, high dynamic range, and sparse sensing. This stands in contrast to whole image frame-wise acquisition by standard cameras. Here, we systematically investigate the implications of event-based sensing in the context of visual motion, or flow, estimation. Starting from a common theoretical foundation, ...
متن کاملAsynchronous frameless event-based optical flow
This paper introduces a process to compute optical flow using an asynchronous event-based retina at high speed and low computational load. A new generation of artificial vision sensors has now started to rely on biologically inspired designs for light acquisition. Biological retinas, and their artificial counterparts, are totally asynchronous and data driven and rely on a paradigm of light acqu...
متن کاملUnusual Event Detection and Localization Using Optical Flow Technique
Video-surveillance systems are becoming more and more independent in the finding and the exposure of anomalous events. The safety of mankind in crowds under disaster situation is one of the most essential concerns of researchers. This paper presents an approach to notice abnormal situations in crowded scenes by analysing the movement aspect and localize the unusual event using clusterization me...
متن کاملMicrofluidic flow rate detection based on integrated optical fiber cantilever.
We demonstrate an integrated microfluidic flow sensor with ultra-wide dynamic range, suitable for high throughput applications such as flow cytometry and particle sorting/counting. A fiber-tip cantilever transduces flow rates to optical signal readout, and we demonstrate a dynamic range from 0 to 1500 microL min(-1) for operation in water. Fiber-optic sensor alignment is guided by preformed mic...
متن کاملAn Event-Based Optical Flow Algorithm for Dynamic Vision Sensors
We present an event-based optical flow algorithm for the Davis Dynamic Vision Sensor (DVS). The algorithm is based on the Reichardt motion detector inspired by the fly visual system, and has a very low computational requirement for each event received from the DVS.
