Image registration for foveated panoramic sensing
Fadi Dornaika, James H. Elder
Article No.: 17
DOI: 10.1145/2168996.2168997

This article addresses the problem of registering high-resolution, small field-of-view images with low-resolution panoramic images provided by a panoramic catadioptric video sensor. Such systems may find application in surveillance and...

Comparison of predictive contract mechanisms from an information theory perspective
Xin Zhang, Tomás Ward, Séamus Mcloone
Article No.: 18
DOI: 10.1145/2168996.2168998

Inconsistency arises across a Distributed Virtual Environment due to network latency induced by state changes communications. Predictive Contract Mechanisms (PCMs) combat this problem through reducing the amount of messages transmitted in return...

Interactive television news
Dan R. Olsen, Derek Bunn, Trent Boulter, Robert Walz
Article No.: 19
DOI: 10.1145/2168996.2168999

A new interactive television experience has been created for watching television news. The goal is to create a news experience that is similar to the way people watch television in their living rooms while giving viewers the power to make choices...

REED: Optimizing first person shooter game server discovery using network coordinates
Grenville Armitage, Amiel Heyde
Article No.: 20
DOI: 10.1145/2168996.2169000

Online First Person Shooter (FPS) games typically use a client-server communication model, with thousands of enthusiast-hosted game servers active at any time. Traditional FPS server discovery may take minutes, as clients create thousands of...

Image label completion by pursuing contextual decomposability
Xiaobai Liu, Shuicheng Yan, Tat-Seng Chua, Hai Jin
Article No.: 21
DOI: 10.1145/2168996.2169001

This article investigates how to automatically complete the missing labels for the partially annotated images, without image segmentation. The label completion procedure is formulated as a nonnegative data factorization problem, to decompose the...

Sprite generation using sprite fusion
Yi Chen, Abhidnya A. Deshpande, Ramazan S. Aygüun
Article No.: 22
DOI: 10.1145/2168996.2169002

There has been related research for sprite or mosaic generation for over 15 years. In this article, we try to understand the methodologies for sprite generation and identify what has not actually been covered for sprite generation. We first...

Collaborative video reindexing via matrix factorization
Ming-Fang Weng, Yung-Yu Chuang
Article No.: 23
DOI: 10.1145/2168996.2169003

Concept-based video indexing generates a matrix of scores predicting the possibilities of concepts occurring in video shots. Based on the idea of collaborative filtering, this article presents unsupervised methods to refine the initial scores...
