The Video Mesh: A Data Structure for Image-based Video Editing
(2009-12-16)
This paper introduces the video mesh, a data structure for representing video as 2.5D "paper cutouts." The video mesh allows interactive editing of moving objects and modeling of depth, which enables 3D effects and ...
Selective Vectorization for Short-Vector Instructions
(2009-12-18)
Multimedia extensions are nearly ubiquitous in today's general-purpose processors. These extensions consist primarily of a set of short-vector instructions that apply the same opcode to a vector of operands. Vector ...
SWIFT: A Narrowband-Friendly Cognitive Wideband Network
(2008-08-17)
Wideband technologies in the unlicensed spectrum can satisfy the ever-increasing demands for wireless bandwidth created by emerging rich media applications. The key challenge for such systems, however, is to allow narrowband ...

Sufficient Conditions for Uniform Stability of Regularization Algorithms
(2009-12-01)
In this paper, we study the stability and generalization properties of penalized empirical-risk minimization algorithms. We propose a set of properties of the penalty term that is sufficient to ensure uniform ?-stability: ...
Perfect and General Virtual Implementation For Perfectly Informed Players
(2009-12-04)
We show that, when the players are perfectly informed about each other, essentially all social-choice functions can be rationally robustly implemented via an extensive-form public-action mechanism that (1) is perfectly ...
Emergent Communication: The evolution of simplistic machines using different communication types
(2009)
The methods of transmitting information may be divided as follows: direct; and, indirect. The âdirectâ method occurs when a creature transmits a signal that other creatures in its local environment can receive. Word of ...
An Adjectival Interface for procedural content generation
(2008)
In this thesis, a new interface for the generation of procedural content is proposed, in which the user describes the content that they wish to create by using adjectives. Procedural models are typically controlled by ...
An adaptive agent architecture for exogenous data sales forecasting
(2006)
In a world of unpredictability and complexity, sales forecasting is becoming recognised as essential to operations planning in business and industry. With increased globalisation and higher competition, more products are ...
A cross-platform usability evaluation of 2D visual tagging systems
(2007)
By encoding 2D bar codes that store URL links, SMS or plain text, 2D visual tags link infonnation about objects in the physical world to online or offline content. The existence of physical world hyperlinks in the fonn of ...
