Long-Term Identity-Aware Multi-Person Tracking for Surveillance Video Summarization
Shoou-I Yu, Yi Yang, Xuanchong Li +1
Multi-person tracking plays a critical role in the analysis of surveillance video. However, most existing work focus on shorter-term (e.g. minute-long or hour-long) video sequences…
Long-short Term Motion Feature for Action Classification and Retrieval
Zhenzhong Lan, Xuanchong Li, Ming Lin +1
We propose a method for representing motion information for video classification and retrieval. We improve upon local descriptor based methods that have been among the most popular…
Beyond Gaussian Pyramid: Multi-skip Feature Stacking for Action Recognition
Zhenzhong Lan, Ming Lin, Xuanchong Li +2
Most state-of-the-art action feature extractors involve differential operators, which act as highpass filters and tend to attenuate low frequency action information. This attenuati…
Temporal Extension of Scale Pyramid and Spatial Pyramid Matching for Action Recognition
Zhenzhong Lan, Xuanchong Li, Alexandar G. Hauptmann
Historically, researchers in the field have spent a great deal of effort to create image representations that have scale invariance and retain spatial location information. This pa…
