Face alignment is an essential task for facial performance capture and expression analysis. Current methods such as random subspace supervised descent method, stage-wise relational dictionary and coarse-to-fine shape searching can ease multi-pose face alignment problem, but no method can deal with the multiple local minima problem directly. In this paper, we propose a sign correlation subspace method...
Most video tracking algorithms including L1 tracker often fail to track correctly under adverse conditions such as object occlusion, disappearance, etc. To address this issue, we propose an improved L1 tracker algorithm called Tracker-2, based on what we call the expanded template which includes the reference template and trail template. The reference template keeps the original features of the target...
High-dimensional data in the real world often resides in low-dimensional subspaces. The state-of-the-art methods for subspace segmentation include Low Rank Representation (LRR) and Sparse Representation (SR). The former seeks the global lowest rank representation but restrictively assumes the independence among subspaces, whereas the latter seeks the clustering of disjoint or overlapped subspaces...
