On Universally Decodable Matrices for Space-Time Coding
The notion of universally decodable matrices (UDMs) was recently introduced by Tavildar and Viswanath while studying slow fading channels. It turns out that the problem of construc...

Efficient Scale-Space Spatiotemporal Saliency Tracking for Distortion-Free Video Retargeting
Video retargeting aims at transforming an existing video in order to display it appropriately on a target device, often in a lower resolution, such as a mobile phone. To preserve a...
