Geometric Median Shapes

open access: yesCoRR, 2018
We present an algorithm to compute the geometric median of shapes which is based on the extension of median to high dimensions. The median finding problem is formulated as an optimization over distances and it is solved directly using the watershed method as an optimizer.

On the Exponential Growth of Geometric Shapes

open access: yesTheoretical Computer Science
In this paper, we explore how geometric structures can be grown exponentially fast. The studied processes start from an initial shape and apply a sequence of centralized growth operations to grow other shapes. We focus on the case where the initial shape is just a single node.

Geometric morphometric analysis of spore shapes improves identification of fungi.

open access: yesPLoS ONE, 2021
Morphology of organisms is an essential source of evidence for taxonomic decisions and understanding of ecology and evolutionary history. The geometric structure (i.e., numeric description of shape) provides richer and mathematically different ...

A Geometric Framework for Stochastic Shape Analysis [PDF]

open access: yesFoundations of Computational Mathematics, 2018
We introduce a stochastic model of diffeomorphisms, whose action on a variety of data types descends to stochastic evolution of shapes, images and landmarks. The stochasticity is introduced in the vector field which transports the data in the Large Deformation Diffeomorphic Metric Mapping (LDDMM) framework for shape analysis and image registration. The
