图3. 本文所提分割模型与手工分割结果比较,上、下两行分别代表两个不同的患者.左、中、右三列分别代表前列腺底部、中部和顶部的切片.绿色轮廓是由经验丰富的医生手工分割结果,红色轮廓是本文模型分割结果

Fig.3. Comparison between the segmentation results with the algorithm proposed in this research and those with ground truth. The upper and lower lines represent two different patients respectively. The left, middle, and right columns represent the slices of the bottom, middle, and top of the prostate, respectively. Green contour is ground truth, while red contour is segmented by our algorithm
