Current morphometric methods that comprehensively measure shape cannot compare the disparate leaf shapes found in seed plants and are sensitive to processing artifacts. We explore the use of persistent homology. a topological method applied as a filtration across simplicial complexes (or more simply. a method to measure topological features of spaces across different spatial resolutio... https://www.roneverhart.com/Verragio-Paradiso-Round-Diamond-Engagement-Ring-Setting-0-55-CTW-p5464/
