A Discriminative CNN Video Representation for Event Detection
Zhongwen Xu, Yi Yang, Alexander G. Hauptmann
In this paper, we propose a discriminative video representation for event detection over a large scale video dataset when only limited hardware resources are available. The focus o…
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…
