GradeScan® Geometric Feature Detection |
Wane GradeScan computes equivalent wane or, at your choice, absolute wane for your appearance grades. Wane dip rules are enforced at Grade Book levels (including surfacing-out conventions) or you can decide to make your rules more stringent for premium grades. GradeScan will find and correctly evaluate steep wane, shallow wane, saddle wane and smooth bark. Skip Technically both wane and skip are "missing wood" but grading inspectors evaluate them differently. GradeScan's geometric algorithms never mistake one for the other so that skip and wane can have independent rules. Skip is classified as light, medium and heavy according to its depth. GradeScan's high geometric resolution also allows detection of very light skip which is skip less than 20 thousandths of an inch deep. The image on the left shows the geometric wane contour in green. Notice the skip in the center of the board. Lucidyne's Skip Finder puts white boxes over the skip areas. We never confuse wane with skip. |
