Top row: Qualitative results of automatically segmented cartilage using B-mode US data as an input to the segmentation method, overlaid on expert manual segmentation (red: false negative, magenta: false positive, white: true positive): (a) Manual segmentation overlaid with RW segmentation. (b) Manual segmentation overlaid on watershed segmentation. (c) Manual segmentation overlaid on graph-cut segmentation. Bottom row: automatically segmented cartilage region overlaid on original B-mode US data: (d) Cartilage region segmented using RW method. (e) Cartilage region segmented using watershed method. (f) Cartilage region segmented using graph-cut method.
