Shape Analysis of Elastic Curves in Euclidean Spaces
TL;DR: This paper introduces a square-root velocity (SRV) representation for analyzing shapes of curves in euclidean spaces under an elastic metric and demonstrates a wrapped probability distribution for capturing shapes of planar closed curves.
Analysis of planar shapes using geodesic paths on shape spaces
TL;DR: This work uses a Fourier basis to represent tangents to the shape spaces and a gradient-based shooting method to solve for the tangent that connects any two shapes via a geodesic.

TL;DR: ECT-induced neuroplasticity in the hippocampus and amygdala relates to improved clinical response and is pronounced in regions with prominent connections to ventromedial prefrontal cortex and other limbic structures.

On Shape of Plane Elastic Curves
TL;DR: In this article, the elastic properties of the curves are encoded in Riemannian metrics on these spaces and shape spaces are used to quantify shape divergence and to develop morphing techniques.

TL;DR: A "spherical" version of the Fisher-Rao metric is proposed that provides closed-form expressions for geodesies and distances, and allows fast computation of sample statistics and an application in planar shape classification is presented.
