Surfactants as a Tool for Coupling Light Into Hydrodynamic Flow: The Influence of Surfactant Hydrophobicity and Head Polarity

Advanced Materials Interfaces, EarlyView.
Reversible light‐induced gradients at solid–liquid interfaces enable controllable interfacial transport via light‐driven diffusioosmosis. We demonstrate directed particle manipulation based on dynamically generated concentration gradients. The mechanism is broadly applicable to cationic, anionic, and non‐ionic surfactants with varying hydrophobicity ...

The Multivehicle Stereo Event Camera Dataset: An Event Camera Dataset for 3D Perception [PDF]

IEEE Robotics and Automation Letters, 2018
Event based cameras are a new passive sensing modality with a number of benefits over traditional cameras, including extremely low latency, asynchronous data acquisition, high dynamic range and very low power consumption. There has been a lot of recent interest and development in applying algorithms to use the events to perform a variety of 3D ...

Event recognition with PTZ cameras

3rd International Conference on Imaging for Crime Detection and Prevention (ICDP 2009), 2009
In this paper, a framework for explicit complex event recognition is proposed. The system extracts relevant features from video streams coming from PTZ cameras in order to detect, classify, and track moving objects in the scene. This information is then processed in order to recognize both simple events (instantaneous events involving a single object ...

Tweeting Cameras for Event Detection

Proceedings of the 24th International Conference on World Wide Web, 2015
We are living in a world of big sensor data. Due to the widespread prevalence of visual sensors (e.g. surveillance cameras) and social sensors (e.g. Twitter feeds), many events are implicitly captured in real-time by such heterogeneous "sensors". Combining these two complementary sensor streams can significantly improve the task of event detection and ...

Space-Time Event Clouds for Gesture Recognition: From RGB Cameras to Event Cameras

2019 IEEE Winter Conference on Applications of Computer Vision (WACV), 2019
The recently developed event cameras can directly sense the motion in the scene by generating an asynchronous sequence of events, i.e., event streams, where each individual event (x, y, t) corresponds to the space-time location when a pixel sensor captures an intensity change.

Compressed Event Sensing (CES) Volumes for Event Cameras

International Journal of Computer Vision
Deep learning has made significant progress in event-driven applications. But to match standard vision networks, most approaches rely on aggregating events into grid-like representations, which obscure crucial temporal information and limit overall performance.
