Dataset for Vascular Bundle Detection in Moso Bamboo

# Dataset for Vascular Bundle Detection in Moso Bamboo © 2026 Lukas Speichinger, Karlsruhe Institute of Technology (KIT), Institue of Engineering Mechanics, Chair of Continuum Mechanics ## Description This repository provides **62 annotated images** in the YOLO‑txt format for training a detection model that identifies vascular bundles in the cross-section of Moso bamboo (*Phyllostachys pubescens*) internodes. The images show radially orientated realizations of the culm wall's mesostrucutre taken by a digital microscop with a 2MP sensor.

Each original image was cropped so that its horizontal borders coincide with the inner and outer bounds of the culm wall. Three bundle types are present, VB-I, VB-II and VB-III, which differ by fiber bundle number. Bounding boxes and class labels were assigned manually based on the study of [[Xu et al.(2021) ]](doi.org/10.1016/J.INDCROP.2021.114164). ##
