Estimating Relative Camera Motion from the Antipodal-Epipolar Constraint
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By John Lim, Nick Barnes, Hongdong Li
Issue Date:October 2010
pp. 1907-1914
This paper introduces a novel antipodal-epipolar constraint on relative camera motion. By using antipodal points, which are available in large Field-of-View cameras, the translational and rotational motions of a camera are geometrically decoupled, allowing...
 
Directions of egomotion from antipodal points
Found in: Computer Vision and Pattern Recognition, IEEE Computer Society Conference on
By John Lim, Nick Barnes
Issue Date:June 2008
pp. 1-8
We present a novel geometrical constraint on the egomotion of a single, moving camera. Using a camera with a large field-of-view (FOV), the optical flow measured at a single pair of antipodal points on the image sphere constrains the set of all possible ca...
 
Estimation of the Epipole using Optical Flow at Antipodal Points
Found in: Computer Vision, IEEE International Conference on
By John Lim, Nick Barnes
Issue Date:October 2007
pp. 1-6
This paper develops an algorithm for estimating the epipole or direction of translation of a moving monocular observer. To this end, we use constraints arising from two points that are antipodal on the image sphere. The antipodal point condition is necessa...
 
Effect of Gender Composition and Negotiation Support Systems in Dyadic Setting
Found in: Hawaii International Conference on System Sciences
By Zhen Wang, John Lim
Issue Date:January 2007
pp. 35
Many empirical studies of negotiation support systems (NSS) have shown that NSS generally improve negotiation performance. While most research on NSS has focused on the functional and structural issues, the investigation of negotiator characteristics is la...
   
Cultural Diversity, Leadership, Group Size and Collaborative Learning Systems: An Experimental Study
Found in: Hawaii International Conference on System Sciences
By John Lim, Yingqin Zhong
Issue Date:January 2005
pp. 11a
Collaborative learning systems (CLS) have received increasing research attention owing to advances in computer-mediated technology and paradigmatic shifts in the educational arena. To understand the circumstances under which the use of CLS would enhance le...
   
Exploring Multilingual Negotiation Support for English-Chinese Dyads: An Experimental Study
Found in: Hawaii International Conference on System Sciences
By John Lim, Yin Ping Yang
Issue Date:January 2005
pp. 37a
The increasing number of international negotiations involving multiple languages necessitates a growing reliance on multilingual support. Whereas empirical studies on negotiation support systems (NSS) have shown that NSS generally improve negotiation perfo...
   
Unlocking the Integrative Potential of Multiparty Negotiation through the Excluded Player: The Role of Negotiation Support Systems from a Coalition Perspective
Found in: Hawaii International Conference on System Sciences
By Xiaojia Guo, John Lim
Issue Date:January 2009
pp. 1-10
This paper investigates the potential role of negotiation support systems (NSS) in supporting multiparty negotiations. Multiparty negotiation is much more complex than dyadic negotiation and warrants separate investigation. Coalition is widely acknowledged...
   
A Multiple-Case Study of The Instructor's Roles in Courseware Development
Found in: Hawaii International Conference on System Sciences
By Na Liu, Cheng Yi, John Lim
Issue Date:January 2009
pp. 1-10
Past literatures on e-learning system and courseware have focused on the system features and on the technologies employed. To integrate IT well with pedagogical principles, it is important to involve instructors in the courseware development. This study se...
   
Cyber Migration: An Empirical Investigation on Factors that Affect Users' Switch Intentions in Social Networking Sites
Found in: Hawaii International Conference on System Sciences
By Zengyan Cheng, Yinping Yang, John Lim
Issue Date:January 2009
pp. 1-11
In recent years, Social Networking Sites (SNSs) have increasingly gained popularity. With the existence of hundreds of such sites, it is not uncommon to have users switching between them. Thus retaining existing users and attracting new users is crucial to...
