    This paper describes an improved computer program to grade hardwood lumber. The program was created as part of a system to automate various aspects of the hardwood manufacturing industry. It enhances previous efforts by considering both faces of the board and provides easy application of species dependent rules. The program can be readily interfaced with a computer vision system (to locate and identify defects without human intervention). While such a computer vision/grading system is still under development, this program has additional merit. Potential applications include online evaluation of lumber grade, training of graders, and yield optimization studies.
