    Virginia Tech and the Southern Research Station of the USDA Forest Service have jointly developed and refined a multiple-sensor lumber-scanning prototype to demonstrate and test applicable scanning technologies (Conners et al. 1997, Kline et al. 1997, Kline et al. 1998). This R&D effort has led to a patented wood color and grain sorting system (Conners and Lu 1998) and a patented defect detection system for lumber (Conners et al. 1999). The objective of the current study is to test the application of this defect detection system on hardwood lumber grading. We will discuss some of our findings to date and discuss what implications they have in the development of automatic hardwood lumber grading systems.
