Project Highlights

eDREAM: Enhancing Driver inteRaction with digital mEdiA through cognitive Monitoring

In the last decade, digital media such as cell phone, FM radio, auxiliary music player, navigation system, and digital controls has had rapid growth in usage by drivers. Close at hand and useful, these technological advancements, however, have also imposed risks to drivers in the form of distraction. To better understand various aspects of driver distraction, the project will investigate what physiological features are affected by arousal, how arousal is defined in terms of physiological measures, and how these measures would be integrated into enhancing driving experience.

Privacy Protected Surveillance Using Secure Visual Object Coding

The Secure Shape and Texture Set Partitioning in Hierarchical Trees (SecST-SPIHT) secure visual object coder allows individual, arbitrarily shaped objects to be efficiently coded (compressed) and encrypted. We use this in surveillance applications to protect the privacy of individuals appearing in the surveillance footage.

Multilinear Subspace Learning (MSL)

This project aims to provide an overview of resources concerned with theories and applications of multilinear subspace learning (MSL). The origin of MSL traces back to multi-way analysis in the 1960s and they have been studied extensively in face and gait recognition. With more connections revealed and analogies drawn between multilinear algorithms and their linear counterparts, MSL has become an exciting area to explore for applications involving large-scale multidimensional (tensorial) data as well as a challenging problem for machine learning researchers to tackle.
