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 ...

Generalized Event Cameras

open access: yes2024 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)
Event cameras capture the world at high time resolution and with minimal bandwidth requirements. However, event streams, which only encode changes in brightness, do not contain sufficient scene information to support a wide variety of downstream tasks.

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.
