Learning a Hierarchy of Discriminative Space-Time Neighborhood Features for Human Action Recognition
14 years 7 months ago
Recent work shows how to use local spatio-temporal features to learn models of realistic human actions from video. However, existing methods typically rely on a predefined spatial...
