11. The method of claim 1 , wherein a value of a parameter associated with the at least one site is a weighted value based at least in part on the corresponding values of such parameter of the set of control points.
12. The method of claim 1 , wherein the at least two hair elements at least partially overlap, and the proposed follicular unit implantation sites are automatically modified or generated such that a density of proposed follicular unit sites in an area of overlap is substantially similar to a density of other proposed follicular unit sites within a non-overlapping portion of the first or the second element.
13. The method of claim 1 , the method comprising selecting a first control point from the first hair element and a second control point from the second hair element, and linking the first and second selected control points such that modification of the first selected control point automatically modifies the second selected control point.
14. The method of claim 1 , the method further comprising performing a procedure on the at least one site according to the planning.
15. The method of claim 1 , the method comprising directing an automated system for hair transplantation to execute the plan to harvest, make sites, or implant follicular units in the body surface.
16. The method of claim 1 , the method comprising generating one or more virtual grid sections corresponding to placement of a skin tensioning or a fiducial locator device on the body surface according to the plan.
17. The method of claim 16 , wherein the one or more virtual grid sections are generated based on an outer contour of the at least two hair elements.
18. The method of claim 16 , wherein the one or more virtual grid sections are generated at least partially based on a size of a skin tensioning device.
