A mixed 0-1 linear programming approach to the computation of all pure-strategy nash equilibria of a finite n -person game in normal form
Wu, Zhengtian; Dang, Chuangyin; Karimi, Hamid Reza; Zhu, Changan; Gao, Qing (Journal article; Peer reviewed, 2014)A main concern in applications of game theory is how to effectively select a Nash equilibrium, especially a pure-strategy Nash equilibrium for a finite n -person game in normal form. This selection process often requires ... -
A mutual GrabCut method to solve co-segmentation
Gao, Zhisheng; Shi, Peng; Karimi, Hamid Reza; Pei, Zheng (Journal article; Peer reviewed, 2013)Co-segmentation aims at segmenting common objects from a group of images. Markov random field (MRF) has been widely used to solve co-segmentation, which introduces a global constraint to make the foreground similar to each ... -
A novel active contour model for unsupervised low-key image segmentation
Mei, Jiangyuan; Si, Yulin; Karimi, Hamid Reza; Gao, Huijun (Journal article; Peer reviewed, 2013)Unsupervised image segmentation is greatly useful in many vision-based applications. In this paper, we aim at the unsupervised low-key image segmentation. In low-key images, dark tone dominates the background, and gray ... -
