- *Abstract
-
As their cost have decreased, video camera usage has proliferated in consumer, commercial and government applications. This growth in video usage is leading to an increased need for tools that can perform rudimentary action recognition on compressed video in order to assist users in focusing on targeted actions within voluminous video footage.
To address this opportunity, researchers at UC Berkeley have developed a computational method that can recognize and localize targeted actions in compressed video data. This real-time method uses compressed domain features that can be extracted with low complexity. This novel technique can localize actions in both space and time. Moreover, it is appearance invariant, and it doesn't require prior segmentation, alignment, stabilization or decompression.
The Berkeley research team tested their method on a large action video database consisting of six actions performed by 25 people under 3 different scenarios. The results compared favorably to existing methods at only a fraction of the computational costs of those previous methods.

Title: High speed video action recognition and localization
Usefulness: High speed video action recognition and localization
Summary: System for detecting and locating an action in a video from the applications. Uses include but are not limited to walking, running, jumping, throwing a punch and action performed by an animate and inanimate actor from video surveillance application, collision-avoidance application for unmanned aerial vehicles, video editing application, video piracy prevention application and viewing application.
Novelty: Action e.g. walking, detecting and locating system for use in e.g. video surveillance application, has employing unit employing similarity value to recognize action or similar action, which occurs in query video and test video
