Abstract: Temporal segmentation of facial gestures from video sequences is an important unsolved problem for automatic facial analysis. Recovering temporal gesture structure from a set of 2D facial features tracked points is a challenging problem because of the difficulty of factorizing rigid and non-rigid motion and the large variability in the temporal scale of the facial gestures. In this paper, we propose a two step approach for temporal segmentation of facial gestures. The first step consist on clustering shape and appearance features into a number of clusters and the second step involves temporally grouping these clusters. Results on clustering largely depend on the registration process. To improve the clustering/registration, we propose a Parameterized Cluster Analysis (PaCA) method that jointly performs registration and clustering. Besides the joint clustering/registration, PaCA solves the rounding off problem of existing spectral graph methods for clustering. After the clustering is p erformed, we group sets of clusters into facial gestures. Several toy and real examples show the benefits of our approach for temporal facial gesture segmentation. (More)
