In several processes of the forest products industry, an in-depth knowledge of log and board
internal features is required and their determination needs fast scanning systems. One of the …

This paper reviews state-of-the-art in nondestructive testing (NDT) and semidestructive
testing (SDT) methods applicable for imaging the condition of structural timber. Both NDT …

This paper reports application of electric, ultrasonic, and georadar tomography for detection
of decay in trees and their comparison with the traditional penetrometer. Their feasibility in …

This paper describes the design and implementation of a machine vision system CATALOG
for detection and classification of some important internal defects in hardwood logs via …

The paper presents the automated on-line system for wood logs 3D geometry scanning. The
system consists of 6 laser triangulation scanners and is able to scan full wood logs which …

Both laboratory and field ultrasonic measurements were carried out to assess the feasibility
of ultrasonic tomography for non-invasive testing of living trees. Trees with internal decay …

An automated system for planning and optimization of lumber production using Machine
Vision and Computed Tomography (CT) is proposed. Cross-sectional CT images of …

The problem of tree assessment is increasingly felt both as a problem of life quality as well
as a problem of safety within the city management. One of the main causes of the collapse of …

The ability to detect defects on hardwood trees and logs holds great promise for the
hardwood forest products industry. At every stage of wood processing, there is a potential for …

The artificial neural network (ANN) model and five traditional statistical regression models
were used to predict four parameters of simulated product recovery (lumber volume, lumber …
