An Improved Mask R-CNN Model for Multiorgan Segmentation

Figure 8

Failure cases. False detection and missed detection segmentation results. Left image is the segmentation result of the 10th slice of a patient, missed detection occurred on the right lung. Right image is the segmentation result of the 115th slice of a patient. The left lung and the right lung areas may be segmented partially (yellow represents the right lung, brown represents the left lung, cyan represents the heart, blue represents PTV, and gray represents CTV). (a) Missed detection. (b) False detection.
