Anatomical properties of wood affect the properties of wood products. In this paper, an automated image analysis method for measuring cross-sectional tracheid dimensions of softwood cores is presented. The images used were single slice, confocal reflected light microscope images. By the use of the proposed method, automatic measurements of radial and tangential lumen diameter, as well as radial cell-wall thickness, of almost all individual tracheids are obtainable.
