TECHNICAL ADVANCE: LeafAnalyser: a computational method for rapid and large-scale analyses of leaf shape variationCaroline Weight, Daniel Parnham, Richard WaitesThe Plant Journal, 2007 View paper
LeafAnalyser has been developed as a tool to perform data collection, collation and analysis. Although aimed at leaves it can in fact be used to investigate the shape of anything that can be scanned. It combines image processing, statistical calculations and real-time 3D rendering to provide a simple to use package that replaces the need to manually measure images and process huge quantities of numbers within a spreadsheet.
