    Description

    In this paper I describe an image analysis system and illustrate with examples the application of automatic quantitative measurement to wood science. Automatic image analysis, a powerful and relatively new technology, uses optical, video, electronic, and computer components to rapidly derive information from images with minimal operator interaction. Such instruments should prove useful to researchers and technologists who use analytical procedures, inspection methods, and investigative techniques that require processing large amounts of data (e.g., fiber length and cellular dimension measurements). Additionally, a system using scanning technology for primary log breakdown and for cutting clear furniture parts from defective boards is proposed. In the system, computerized axial tomography - known popularly as CAT scan - nondestructively locates defects within log interiors. A computer program then positions the log to yield boards of maximum value. Optical scanning methods identify and locate defects on board surfaces. The defect data is used to compute complex cutting patterns to minimize yield of clear pieces using a laser-cutting device.
