RegionDilation
RegionDilation[reg, r] gives the dilation of the region reg by a disk of radius r centered at the origin.
RegionDilation[reg1, reg2]gives the dilation of the region reg1 by the region reg2.RegionDilation[reg1, reg2, {u, v}]gives the dilation of reg1 scaled by a factor u and reg2 scaled by a factor v.
Region dilation is a morphological operation that expands a region by a specified amount.
