Leonardo vindicated: Pythagorean trees for minimal reconstruction of the natural branching structures
Dymitr Ruta, Corrado Mio, Ernesto Damiani·November 12, 2024
Summary
The paper explores Pythagorean trees, fractal designs resembling natural tree structures, aiming to create the most realistic models. Researchers developed an algorithm using Convolutional Neural Networks (CNNs) to generate these trees, adjustable for various parameters, and tested their realism. The study identified optimal parameters for the trees, translating them into scales and angles for branches, enhancing our understanding of natural tree branching. The research supports Leonardo da Vinci's branching rule and golden ratio, arguing that flexible fractal trees can generate artificial examples for training robust detectors of different tree species. The study highlights the engineering efficiency of natural trees, focusing on water transport, wind resistance, and light access. The team claims fractals offer a simple, essential description for tree structure modeling.
