%description
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.
