Beyond Gaussian Pyramid: Multi-skip Feature Stacking for Action Recognition

CVPR 2015 Zhenzhong LanMing LinXuanchong LiAlexander G. HauptmannBhiksha Raj

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 attenuation introduces bias to the resulting features and generates ill-conditioned feature matrices... (read more)
