Hi folks, I signal you this new contribution presenting a new 2D explicit formula for Parallel Transport in the Size and Shape Space for the analysis of morphological trajectories.
Varano, V., Gabriele, S., Teresi, L., Dryden, I., Puddu, P., Torromeo, C., & Piras, P. 2015. Comparing shape trajectories of biological soft tissues in the size-and-shape space. In Biomat 2014: International Symposium on Mathematical and Computational Biology (pp. 351-365). Our approach is suited for 2D-configurations only (as we exploit the potential of complex notation) constituted by homologous landmarks and identifying very different initial shapes that experience any kind of deformation (such as in allometry). The aim is to look at pure deformation patterns occurring within groups by filtering out initial inter-group differences.This is achieved by properly setting the Levi Civita Parallel Transport in the Riemannian Size and Shape Space. Albeit it is not cited in the text, a R function exists to perform the analyses described in the paper. In the case you cannot download the paper here http://www.worldscientific.com/worldscibooks/10.1142/9566 please email me to have the article and/or the R function. Any advice and/or function testing is welcome.
