4 years ago It's because the start and end points are inclusive so p includes segments 3, 4, and 5 and g includes segments 4, 5 and 6. The union is segments 3, 4, 5, and 6 and the intersection is segments 4 and 5. This iou should be 0.5.

if p=[3,5] g=[4,6] then the iou should be (5-4)/(6-3)=0.33333 but iou(p,g)=0.5 Did I get it wrong？
