Image segmentation for defect detection on veneer surfaces

Creator:

Zhong, Yuan, 1956-

Abstract:

Machine vision is widely used in scientific areas and non-wood using industries, but the extreme variability of wood has limited its adoption by forest products industries. However, it is now becoming a key factor in further automation of the forest products industry. As a very important part of machine vision,...

Dielectric properties of defects on wood surfaces

Creator:

Forrer, Johannes B.

Abstract:

Raw material costs and limited material availability and quality have created significant interest in and opportunities for the application of nondestructive evaluation techniques to improve wood processing technologies. The incentives come from the desire to 1) manufacture the highest valued product, 2) conserve the amount of raw material used, 3)...

Integration of an expert system and dynamic programming approach to optimize log breakdown using 3-dimensional log and internal defect shape information

Creator:

Zeng, Yimin

Abstract:

A computer program, SAW3DG, was developed to optimize log breakdown using 3-dimensional log and internal defect shapes. The program was based on SAW3D, a log breakdown optimization program considering only 3-dimensional log shape. SAW3D was modified to include internal log defects in 3-dimensional representation and integrated with SLGRADER, an expert...
