Comparing Curves in Homogeneous Spaces
Zhe Su, Eric Klassen, Martin Bauer
Of concern is the study of the space of curves in homogeneous spaces. Motivated by applications in shape analysis we identify two curves if they only differ by their parametrizatio…
The Square Root Velocity Framework for Curves in a Homogeneous Space
Zhe Su, Eric Klassen, Martin Bauer
In this paper we study the shape space of curves with values in a homogeneous space , where is a Lie group and is a compact Lie subgroup. We generalize the square…
Nonparametric Spherical Regression Using Diffeomorphic Mappings
Michael Rosenthal, Wei Wu, Eric Klassen +1
Spherical regression explores relationships between variables on spherical domains. We develop a nonparametric model that uses a diffeomorphic map from a sphere to itself. The rest…
Phase-Amplitude Separation and Modeling of Spherical Trajectories
Zhengwu Zhang, Eric Klassen, Anuj Srivastava
This paper studies the problem of separating phase-amplitude components in sample paths of a spherical process (longitudinal data on a unit two-sphere). Such separation is essentia…
Video-Based Action Recognition Using Rate-Invariant Analysis of Covariance Trajectories
Zhengwu Zhang, Jingyong Su, Eric Klassen +2
Statistical classification of actions in videos is mostly performed by extracting relevant features, particularly covariance features, from image frames and studying time series as…
