retroDeform3d: symmetrize a bilateral landmark configuration

In Morpho: Calculations and Visualisations Related to Geometric Morphometrics

symmetrize a bilateral landmark configuration

Description

symmetrize a bilateral landmark configuration by removing bending and stretching

Usage

retroDeform3d(mat, pairedLM, hmult = 5, alpha = 0.01)

Arguments

mat	matrix with bilateral landmarks
pairedLM	2-column integer matrix with the 1st columns containing row indices of left side landmarks and 2nd column the right hand landmarks
hmult	factor controlling the bandwidth for calculating local weights (which will be hmult * average distance between landmarks and their closest neighbour).
alpha	factor controlling spacing along x-axis

Value

deformed	matrix containing deformed landmarks
orig	matrix containing original landmarks
