Figure Lengend Snippet: Comparison of segmentation results obtained by three different image segmentation methods in the R-T plane of a local latewood region within an oak growth ring, i.e., the Local Chan-Vese method (red dashed line), the Global Chan-Vese method (yellow dotted line), and Otsu’s grey level thresholding method (blue solid line). a Greyscale image with high phase contrast between cell cavities (black/dark grey) and cell walls (medium grey/light grey). b Greyscale image with medium phase contrast between cell cavities (dark grey/medium grey) and cell walls (medium grey/light grey). The contrast and variation in grey scale levels defining the two figures above are representative of the entire scanning volume of samples A and B (colour figure online)

Article Snippet: In addition, MATLAB allows using a standard version of Otsu’s grey level thresholding method, which is employed in the comparison study presented in Sect. "
