Below is the result I got, and each row is hierarchy details of corresponding contour. For eg, first Below is the result I got, and each row is hierarchy details of corresponding contour. For eg, first
row corresponds to contour 0. Next contour is contour 1. So Next = 1. There is no previous contour, row corresponds to contour 0. Next contour is contour 1. So Next = 1. There is no previous contour,
so Previous = 0. And the remaining two, as told before, it is -1. so Previous = -1. And the remaining two, as told before, it is -1.
