Fast Global Motion Estimation via Modified ILSE Method (2009)
Jia Wang, Hanqing Lu, Qingshan Liu
This paper presents a Modified ILSE technique for global motion estimation where Gradient Thresholding (GT)is used to analyze and preprocess the image blocks before motion estimation.Bymeans of...
A Component Based Deformable Model for Generalized Face Alignment (2008)
Yuchi Huang, Qingshan Liu, Dimitris Metaxas
This paper presents a component based deformable model for generalized face alignment, in which a novel bistage statistical framework is proposed to account for both local and global shape...
Shot Classification in Broadcast Soccer Video (2008)
Xiaofeng Tong, Qingshan Liu, Hanqing Lu
In this paper, we present an effective hierarchical shot classification scheme for broadcast soccer video. We first partition a video into replay and non-replay shots with replay logo detection....
Topology-Preserved Diffusion Distance for Histogram Comparison (2008)
Wang Yan, Qiqi Wang, Qingshan Liu, Hanqing Lu, Songde Ma
In most previous works, histograms are simply treated as n-dimensional arrays or even reshaped into vectors when measuring the distances between them. However many histograms have their intrinsic...

In this paper, we present an effective hierarchical shot classification scheme for broadcast soccer video. We first partition a video into replay and non-replay shots with replay logo detection....
A multimodal scheme for program segmentation and representation in broadcast video streams (2008)
Wang, Jinqiao, Duan, Lingyu, Liu, Qingshan, Lu, Hanqing, Jin, Jesse S.
With the advance of digital video recording and playback systems, the request for efficiently managing recorded TV video programs is evident so that users can readily locate and browse their favorite...
Solving the Small Sample Size Problem of LDA (2002)
Rui Huang, Qingshan Liu, Hanqing Lu, Songde Ma
The small sample size problem is often encountered in pattern recognition. It results in the singularity of the within-class scatter matrix Sw in Linear Discriminant Analysis (LDA). Different methods...
