Research Objective No. 3, MATLAB code

Version_2026_03_03. This is the first version of code for automatic detection and vectorization of extracted elements in an image. Its current workflow makes it possible to identify the color spectrum, segment individual elements, and subsequently vectorize them. At present, the issues of shadows and poor input image quality have not yet been resolved.Related publications:Vrtal, P., Svatý, Z., Kohout, T., Nouzovský, L., & Blodek, T. (2025).
