What is a convex hull, and how is it used in robotics and computer vision? Use the gift-wrapping algorithm to find the convex hull for the following set of points in a 2D plane: {{0,0), (2,3), (4,2), (5,5), (1,4), (3,1), (4,4), (6,1), (7,3), (5,6) }. give the answer so that I can write in exam that way.
