Lory 1.0: Model-based Estimation of Local Shape Deformations

LORY implements the methods described in Marquez et al. (2012) for the estimation of shape variables that measure local differences in shape between individual samples and their Procrustes mean. “Local” refers herein to infinitesimal differences in shape mapped continuously over entire configurations; these differentials give rise to shape variables that differ from other variables such as Procrustes residuals or Partial Warp scores both in their intent and interpretation. LORY’s main output consists of shape variables that can be individually interpreted as local changes in infinitesimal area relative to a reference configuration (i.e., the sample Procrustes mean). Throughout this guide, we refer to these changes as local deformations.
