Specific examples of features and representations include work on superpixels for representing images, motion features for human action recognition, and our bag-of- words model for video sequences. We have developed variants of machine learning algorithms for models such as the hidden Conditional Random Field (hCRF) and Latent Dirichlet Allocation (LDA) to implement these ideas.
