Bayesian Clustering of Shapes of Curves

Unsupervised clustering of curves according to their shapes is an important problem with broad scientific applications. The existing model-based clustering techniques either rely on simple probability models (e.g., Gaussian) that are not generally valid for shape analysis or assume the number of clusters. We develop an efficient Bayesian method to cluster curve data using an elastic shape metri...

Bayesian Alignment of Similarity Shapes.

We develop a Bayesian model for the alignment of two point configurations under the full similarity transformations of rotation, translation and scaling. Other work in this area has concentrated on rigid body transformations, where scale information is preserved, motivated by problems involving molecular data; this is known as form analysis. We concentrate on a Bayesian formulation for statisti...

Predictability of shapes of intraday price curves

We develop a statistical framework, based on functional data analysis, for testing the hypothesis of the predictability of shapes of intraday price curves. We derive test statistics based on signs of the scores of the functional principal components. We establish its asymptotic properties under the null and alternative hypotheses, and demonstrate via simulations that it has excellent finite sam...

Matching of shapes bound by freeform curves

Matching and retrieval of shapes, both in two and three dimensions, have been a topic of interest to researchers in the field of computer graphics, vision and geometric modeling for at least a decade. In this paper, a shape is assumed to be represented as set of freeform curved boundaries. A prominent approach to matching curved outline is the graph-based approach, where a skeleton is used as a...
