Fig. 6From: Isolating phyllotactic patterns embedded in the secondary growth of sweet cherry (Prunus avium L.) using magnetic resonance imagingIsolating phyllotactic features in the boundary image. a The boundary image, created by assembling the means along each radial direction in the polar slices. Rows correspond to polar coordinates and columns slices. b The thresholded boundary image, created using Otsu’s method. c Cylindrical Bravais lattice of nodes, with 2- and 3-parastichies shown. The blob corresponding to node 26 was added by choosing a less restrictive threshold for that regionBack to article page
