Evaluation of the tissue segmentation method. (a) Volume overlap for individual channel segmentation result and that for fusion result. The average overlaps of four single-channel segmentations and the fusion result are 0.44±0.08, 0.48±0.13, 0.60±0.08, 0.57±0.07, and 0.63±0.04, respectively. (b) Volume agreement for individual channel segmentation result and that for fusion result. The average agreements of four single-channel segmentation results and the fusion result are 0.66±0.18, 0.84±0.23, 0.88±0.05, 0.92±0.08, and 0.94±0.04, respectively.
