What is the cost of adding a constraint in linear least squares?
Ramakrishna Kakarala, Jun Wei
Although the theory of constrained least squares (CLS) estimation is well known, it is usually applied with the view that the constraints to be imposed are unavoidable. However, th…
Perceptually Motivated Shape Context Which Uses Shape Interiors
Vittal Premachandran, Ramakrishna Kakarala
In this paper, we identify some of the limitations of current-day shape matching techniques. We provide examples of how contour-based shape matching techniques cannot provide a goo…
A phase-sensitive method for filtering on the sphere
Ramakrishna Kakarala, Philip Ogunbona
This paper examines filtering on a sphere, by first examining the roles of spherical harmonic magnitude and phase. We show that phase is more important than magnitude in determinin…
Parametric annealing: a stochastic search method for human pose tracking
Prabhu Kaliamoorthi, Ramakrishna Kakarala
Model based methods to marker-free motion capture have a very high computational overhead that make them unattractive. In this paper we describe a method that improves on existing…
On the Fourier transform for a symmetric group homogeneous space
Ramakrishna Kakarala
By using properties of the Young orthogonal representation, this paper derives a simple form for the Fourier transform of permutations acting on the homogeneous space of -dimens…
The bispectrum as a source of phase-sensitive invariants for Fourier descriptors: a group-theoretic approach
Ramakrishna Kakarala
This paper develops the theory behind the bispectrum, a concept that is well established in statistical signal processing but not, until recently, extended to computer vision as a…
