4DCov: A Nested Covariance Descriptor of Spatio-Temporal Features for Gesture Recognition in Depth Sequences


In this paper we propose a novel covariance-based framework for the robust characterization and classification of human gestures in 3D depth sequences. The proposed 4DCov descriptor uses the notion of covariance to create compact representations of complex interactions between variations of 3D features in the spatial and temporal domain, instead of using… (More)
