Figure 17.

Some examples of FN and FP detections. Similar to Fig. 9, one row represents one object. Rows 1 and 2 are two FNs, which are a 30 mm flat mass and a 5 mm polyp on the fold. The last three rows are three FPs, where rows 3 and 4 are two nontagged hard stool balls and the last row is a normal polypoid bump on the fold.
