Unsupervised Learning of Human Action Categories Using Spatial-Temporal Words
TL;DR: A novel unsupervised learning method for human action categories that can recognize and localize multiple actions in long and complex video sequences containing multiple motions.
Proceedings ArticleDOI
Unsupervised Learning of Human Action Categories Using Spatial-Temporal Words.
TL;DR: The approach is not only able to classify different actions, but also to localize different actions simultaneously in a novel and complex video sequence.

Facial expression decomposition
Hongcheng Wang,Ahuja +1 more
TL;DR: A novel approach for facial expression decomposition - higher-order singular value decomposition (HOSVD), a natural generalization of matrix SVD is proposed, which learns the expression subspace and person subspace from a corpus of images showing seven basic facial expressions.
Journal ArticleDOI
Out-of-core tensor approximation of multi-dimensional matrices of visual data
TL;DR: Experimental results indicate that the techniques in this paper can not only process out-of-core data, but also achieve higher compression ratios and quality than previous methods.
