A Boundary Construction Algorithm for a Complex Planar Point Set

Table 4

Comparison of the simulated experimental result (uniform distribution point set with holes).

Algorithm	Parameter value	Rough state of the boundary	Note
		Rough	Fails to extract the hole boundary
		Moderate	Fails to extract the hole boundary
		Fine	Fails to extract the hole boundary
		Rough	The hole boundary is extracted, but the shape is quite different from that of the actual situation
		Moderate	The hole boundary is extracted, but the number of holes is different from that of the actual situation
		Fine	The hole boundary is extracted, but the number of holes is different from that of the actual situation
Proposed algorithm		Rough	The hole boundary is extracted, but the number of holes is different from that of the actual situation
		Moderate	The hole boundary is extracted with good effect
		Fine	The hole boundary is extracted with good effect
