Robust View Transformation Model For Gait Recognition Shuai Zheng TNT group meeting 1/12/2011
Outline • Paper Tracking • Robust view transformation model for gait recognition
Paper Tracking • Context-aware fusion: A case study on fusion of gait and face for human identification in video, 2010, Pattern Recognition. Comments: This paper introduce how to combine multi biometrics in context-aware way. Great summary for the existing work. New trends in long distance biometrics.
Paper Tracking • Effective Unconstrained Face Recognition by Combining Multiple Descriptors and Learned Background Statistics.2010, PAMI. Comments: How to write a experimental paper? That’s a model.
Paper Tracking • Cost-sensitive Face Recognition, Zhi-Hua Zhou, PAMI, 2010. Comments: Good motivation: False identification, false rejection, false acceptance are three different criteria, how to consider the whole cases together? To reduce the expectation of whole cost? Multiclass cost-sensitive KLRseems the point of the paper.

Robust view transformation model for gait recognition • Motivation • Motivation • Motivation from related work • Introduction • Experimental results • Conclusions and Future work
Motivation • Robust gait representation should be robust to appearance variation caused by the change in viewing angle, carrying or wearing condition.
Motivation from related work • Shared gait representation subspace should be assumed as low-rank. Related Work Handmade Low-Rank Truncated Singular Decomposition (TSVD) seems achieved better than original SVD in recent papers on multi-view gait recognition. Robust low-rank method achieved exciting performance in background modeling, face recognition.
Introduction We present a Robust View Transformation model and Partial Least Square feature selection algorithm for multi-view gait recognition.

Introduction GEI
Experimental results A Bag? Remove it as noise. A overcoat? Remove it as noise. See? What a impressive results of robust View Transformation model for gait representation!
Conclusions • The proposed method achieves significant performance on the multi-view gait recognition dataset with additional variations caused by wearing or carrying condition change.
Future work sequel • How about the improved low-rank method for other challenge gait recognition dataset? • How about that for visual surveillance system? • Can we achieve super gait recognition? Achieved 99% recognition rates at any viewing angle? How about combine the method with rectified method?
