Automatic Temporal Alignment of AV Data

Philip Neil Garner, John David Scott Dines, Danil Korchagin

In this paper, we describe the automatic audio-based temporal alignment of audio-visual data, recorded by different cameras, camcorders or mobile phones during social events like high school concerts. All recorded data is temporally aligned with a common m ...

The Big Picture on Small Screens Delivering Acceptable Video Quality in Mobile TV

Hendrik Ole Knoche

Mobile TV viewers can change the viewing distance and (on some devices) scale the picture to their preferred viewing ratio, trading off size for angular resolution. We investigated optimal trade-offs between size and resolution through a series of studies. ...

Sampling Urban Mobility through On-line Repositories of GPS Tracks

We analyze urban mobility by relying on the short-term mobility traces gathered from a publicly available web-based repository of GPS tracks - the Nokia Sports Tracker service. All mobility traces are obtained from a set of kml files. We show how the data ...

Predicting User-Cell Association in Cellular Networks from Tracked Data

Jean-Yves Le Boudec

We consider the problem of predicting user location in the form of user-cell association in a cellular wireless network. This is motivated by resource optimization, for example switching base transceiver stations on or off to save on network energy consump ...

Automatic Temporal Alignment of AV Data with Confidence Estimation

Philip Neil Garner, John David Scott Dines, Danil Korchagin

In this paper, we propose a new approach for the automatic audio-based temporal alignment with confidence estimation of audio-visual data, recorded by different cameras, camcorders or mobile phones during social events. All recorded data is temporally alig ...

Out-of-Scene AV Data Detection

Danil Korchagin

In this paper, we propose a new approach for the automatic audio-based out-of-scene detection of audio-visual data, recorded by different cameras, camcorders or mobile phones during social events. All recorded data is clustered to out-of-scene and in-scene ...
