In this paper, we present a novel human activity recognition approach that only requires a single video example per activity. We introduce the paradigm of active video composition, which enables one-example recognition of complex activities. The idea is to automatically create a large number of semi-artificial training videos called composed videos by manipulating an original human activity vid...

The evaluation of the platform is made through logs anal...

The advent of video-sharing sites such as YouTube has led to an unprecedented Internet delivery of community-contributed video content. However, most of these videos are not quality-controlled. This paper reports a first attempt towards assessing web videos in terms of visual quality with significant tests on 30k web videos. We regard the quality assessment as a two-class classification problem...

In this paper, we propose a method to realize compound video (multiple videos on a layout) delivery service for mobile terminals. In the proposed method, we introduce proxies which receive multiple videos from corresponding servers and produce a composite video from the received videos in real-time according to the layouts which users specify. However, if users require sets of videos with sligh...

This paper proposes a new representation to explain and predict popularity evolution in social media. Recent work on social networks has led to insights about the popularity of a digital item. For example, both the content and the network matters, and gaining early popularity is critical. However, these observations did not paint a full picture of popularity evolution; some open questions inclu...

Previous literature suggests that YouTube is extensively used to share health information. While pre-exposure pr...
