Profiling fungal degradation of Scots pine sapwood by short wave infrared hyperspectral image analysis
2020 - IRG/WP 20-20667
Hyperspectral image analysis of Scots pine sapwood wood affected by decay fungi has been carried out as part of a Ph.D. thesis within the project Remote Inspection of Wooden Utility Poles (RIWUP).
In a lab experiment, Petri-dishes with Scots pine sapwood samples on malt agar medium were infected with two types of decay fungi, a brown rot and a white rot. The wood samples were scanned with a HySpe...

Application of diverse hyperspectral imaging systems for evaluation of heritage objects
2020 - IRG/WP 20-10971
Advanced imaging techniques are able to non-invasively characterize, monitor and evaluate the impact of conservation treatments on cultural heritage (CH) objects. In this specific field, hyperspectral imaging (HI) allows non-destructive characterization of materials by identifying and characterizing colouring agents, binders and protective coatings as constituents of an object’s original constru...

Investigating wood anatomical factors influencing the treatability of refractory southern pine- an imaging approach
2023 - IRG/WP 23-40975
Southern pine sapwood is non-durable, and preservative treatment is necessary to protect it against biological degradation. According to AS 1604.1 2021, timber products must have their sapwood fully treated with preservatives for various applications and hazard classes. However, there is a growing industry concern over the refractory sections of sapwood, which are untreated pockets of wood that do...
