[Concept] Convex Hull 2d

2d convex hull associated to a shape

Convex Hull 2d measure finds the smallest polygon containing to each shape. The results are subsets of the point describing the input shapes.

If the shape contains holes, they are deleted and the convex hull does not contain the holes.

Here is an example of the convex hulls calculated from an input image :
