Review: Traceability of round wood within the wood supply chain An overview of recent results
: 44 - 50
A cooperation between the University of Applied Sciences Salzburg, located in Kuchl, and the University of Salzburg is working on a fingerprint of digital log end images of cross sections of round wood. Thereby round wood should be able to be identified within the wood supply chain by means of two digital images, whereas the first image is taken in the forest after felling and the second is taken in sawmill. Very similar to a human fingerprint, the pith location and annual rings in the cross section of round wood should provide biometric features that can be used for traceability purposes. Recent results showed, that, first, tracking round wood by means of such biometric features is inherently possible, and, second, how such features can be extracted from digital images.
