CTRing - Density Profiles of Wood from CT Scan Images
Computerized tomography (CT) can be used to assess certain
wood properties when wood disks or logs are scanned. Wood
density profiles (i.e. variations of wood density from pith to
bark) can yield important information used for studies in
forest resource assessment, wood quality and dendrochronology
studies. The first step consists in transforming grey values
from the scan images to density values. The packages then
proposes a unique method to automatically locate the pith by
combining an adapted Hough Transform method and a
one-dimensional edge detector. Tree ring profiles (average ring
density, earlywood and latewood density, ring width and percent
latewood for each ring) are then obtained.
