Dynamic Template Tracking and Recognition
Rizwan Chaudhry, Gregory Hager, Rene Vidal
In this paper we address the problem of tracking non-rigid objects whose local appearance and motion changes as a function of time. This class of objects includes dynamic textures…
Sparse Subspace Clustering: Algorithm, Theory, and Applications
Ehsan Elhamifar, Rene Vidal
In many real-world problems, we are dealing with collections of high-dimensional data, such as images, videos, text and web documents, DNA microarray data, and more. Often, high-di…
Generalized Principal Component Analysis (GPCA)
Rene Vidal, Yi Ma, Shankar Sastry
This paper presents an algebro-geometric solution to the problem of segmenting an unknown number of subspaces of unknown and varying dimensions from sample data points. We represen…
Riemannian Consensus for Manifolds with Bounded Curvature
Roberto Tron, Bijan Afsari, René Vidal
Consensus algorithms are popular distributed algorithms for computing aggregate quantities, such as averages, in ad-hoc wireless networks. However, existing algorithms mostly addre…
