Semantic action recognition by learning a pose lexicon

作者:

Highlights:

• A novel semantic representation, pose lexicon, is proposed for action recognition.

• An extended hidden Markov alignment model is developed to learn a pose lexicon.

• A semantic action recognition method that is capable of zero-shot recognition is developed upon the lexicon.

• The efficacy of the proposed learning and recognition algorithms were evaluated on five datasets using cross-subject, cross-dataset and zero-shot protocols.
