Bi-Modal Biometric Authentication on Mobile Phones in Challenging Conditions

This paper examines the issue of face, speaker and bi-modal authentication in mobile environments when there is significant condition mismatch. We introduce this mismatch by enrolling client models on high quality biometric samples obtained on a laptop com ...

A 240×180 10mW 12us latency sparse-output vision sensor for mobile applications

This paper proposes a 0.18um CMOS vision sensor that combines event driven asynchronous readout of temporal contrast with synchronous frame-based active pixel sensor readout of intensity. The sensor is suitable for mobile applications because it allows low ...

Where to go from here? Mobility prediction from instantaneous information

Patrick Thiran, Matthias Grossglauser, Ehsan Kazemi, Vincent Etter, Mohamed Kafsi

We present the work that allowed us to win the Next-Place Prediction task of the Nokia Mobile Data Challenge. Using data collected from the smartphones of 80 users, we explore the characteristics of their mobility traces. We then develop three families of ...

Mitigating Anonymity Challenges in Automated Testing and Debugging Systems

George Candea, Silviu Andrica

Modern software often provides automated testing and bug reporting facilities that enable developers to improve the software after release. Alas, this comes at the cost of user anonymity: reported execution traces may identify users. We present a way to mi ...

Look up!: Your Future is in the Cloud

James Richard Larus

The "Cloud" is a wonderfully expansive phrase used to denote computation and data storage centralized in a large datacenter and elastically accessed across a network. The concept is not new; web sites and business servers have run in datacenters for a long ...

Rare is Interesting: Connecting Spatio-Temporal Behavior Patterns with Subjective Image Appeal

Sabine Süsstrunk, Gökhan Yildirim

We analyze behavior patterns and photographic habits of the Nokia Mobile Data Challenge (NMDC) participants using GPS and timestamp data. We show that these patterns and habits can be used to estimate image appeal ratings of geotagged Flickr images. In ord ...

A 240x180 120dB 10mW 12us-latency sparse output vision sensor for mobile applications

This paper proposes a CMOS vision sensor that combines event-driven asychronous readout of temporal contrast with synchronous frams-based active pixel sensor (APS) readout of intensity. The image frames can be used for scene content analysis and the tempor ...
