The current study examined the impact of 3D TV watching on neurophysiological responses and cognitive functioning as compared with two-dimensional TV (2D TV) watching. METHODS A total of 72 individuals were randomly assigned to...

We present a system that automatically tags videos, i.e. detects high-level semantic concepts like objects or actions in them. To do so, our system does not rely on datasets manually annotated for research purposes. Instead, we propose to use videos from online portals like youtube.com as a novel source of training data, whereas tags provided by users during upload serve as ground truth annotat...

Activity recognition is an open domain which can be used in a wide spectrum of applications, ranging from video surveillance to monitoring and assisting children, elderly or sick people. Some prior work on activity recognition focuses on identifying all occurrences of a specific type of activity. In more general activity recognition settings however (e.g., Ambient Assisted Living), a system sho...
