Sensorless Pose Determination using Randomized Action Sequences
Pragna Mannam, Alexander Volkov, Robert Paolini +2
This paper is a study of 2D manipulation without sensing and planning, by exploring the effects of unplanned randomized action sequences on 2D object pose uncertainty. Our approach…
Quantizing Euclidean motions via double-coset decomposition
Christian Wülker, Gregory S. Chirikjian
Concepts from mathematical crystallography and group theory are used here to quantize the group of rigid-body motions, resulting in a "motion alphabet" with which to express robot…
Fourier-Zernike Series of Convolutions on Disks
Arash Ghaani Farashahi, Gregory S. Chirikjian
This paper presents a systematic study for analytic aspects of Fourier-Zernike series of convolutions of functions supported on disks. We then investigate different aspects of the…
Parallelization of the FFT on SO(3)
Denis-Michael Lux, Christian Wülker, Gregory S. Chirikjian
In this paper, a work-optimal parallelization of Kostelec and Rockmore's well-known fast Fourier transform and its inverse on the three-dimensional rotation group SO(3) is designed…
Signal Alignment for Humanoid Skeletons via the Globally Optimal Reparameterization Algorithm
Thomas W. Mitchel, Sipu Ruan, Gregory S. Chirikjian
The general ability to analyze and classify the 3D kinematics of the human form is an essential step in the development of socially adept humanoid robots. A variety of different ty…
The Globally Optimal Reparameterization Algorithm: an Alternative to Fast Dynamic Time Warping for Action Recognition in Video Sequences
Thomas Mitchel, Sipu Ruan, Yixin Gao +1
Signal alignment has become a popular problem in robotics due in part to its fundamental role in action recognition. Currently, the most successful algorithms for signal alignment…
Non-Abelian Fourier Series on
Arash Ghaani Farashahi, Gregory S. Chirikjian
This paper discusses computational structure of coefficients of non-Abelian Fourier series on the right coset space expressed in the trigonometric ba…
