An automated method for tree-ring delineation based on active contours guided by DT-CWT complex coefficients in photographic images: Application to Abies alba wood slice images
Our method can be used to delineate successive concentric tree-rings in Abies alba images. We coupled the Q-Shift DT-CWT and the points-based active contour model. Notions such as attraction power and orientation simulate an external force field. Our method performed as well as experts delineations on 200 tree-rings.
