The XyloTron: Flexible, Open-Source, Image-Based Macroscopic Field Identification of Wood Products [PDF]

Frontiers in Plant Science, 2020
Forests, estimated to contain two thirds of the world’s biodiversity, face existential threats due to illegal logging and land conversion. Efforts to combat illegal logging and to support sustainable value chains are hampered by a critical lack of ...

Field-Deployable Computer Vision Wood Identification of Peruvian Timbers [PDF]

Frontiers in Plant Science, 2021
Illegal logging is a major threat to forests in Peru, in the Amazon more broadly, and in the tropics globally. In Peru alone, more than two thirds of logging concessions showed unauthorized tree harvesting in natural protected areas and indigenous ...

Imaged based identification of colombian timbers using the xylotron: a proof of concept international partnership

Colombia Forestal, 2021
Field deployable computer vision wood identification systems can play a key role in combating illegal logging in the real world. This work used 764 xylarium specimens from 84 taxa to develop an image data set to train a classifier to identify 14 ...

Predicting Hardwood Porosity Domains: Toward Cascading Computer-Vision Wood Identification Models

BioResources
Prior work on computer-vision wood identification (CVWID) for North American hardwoods yielded two independent deep learning models – a  22-class model for diffuse-porous woods and a 17-class model for ring-porous woods – but did not address semi-ring ...

Delving into the Porosity Domain Continuum in Hardwood Growth Rings: What Can We Learn from Computer Vision Wood Identification Models?

BioResources
Hardwood porosity domains (diffuse-, semi-ring-, and ring-porosity) exist along a spectrum with some taxa embodying only one porosity domain and others spanning more than one. A cascading model scheme involving a root-level porosity classifier and second-
