描述

interjacentinterjacentInterjacentInterjacentInterjacentinterjacent partitions the image plane using the regions given in RegionRegionRegionRegionregionregion. The result is a region containing the extracted separating lines. The following modes of operation can be used:

'medial_axis'

This mode is used for regions that do not touch or overlap. The operator will find separating lines between the regions which partition the background evenly between the input regions. This corresponds to the following calls:

Example：

complement('full',Region,Tmp)complement("full",Region,Tmp)Complement("full",Region,Tmp)Complement("full",Region,Tmp)Complement("full",Region,Tmp)complement("full",Region,Tmp)

skeleton(Tmp,Result)skeleton(Tmp,Result)Skeleton(Tmp,Result)Skeleton(Tmp,Result)Skeleton(Tmp,Result)skeleton(Tmp,Result)

'border'

If the input regions do not touch or overlap this mode is equivalent to boundary(Region,Result)boundary(Region,Result)Boundary(Region,Result)Boundary(Region,Result)Boundary(Region,Result)boundary(Region,Result), i.e., it replaces each region by its boundary. If regions are touching they are aggregated into one region. The corresponding output region then contains the boundary of the aggregated region, as well as the one pixel wide separating line between the original regions. This corresponds to the following calls:

Example：

boundary(Region,Tmp1,'inner')boundary(Region,Tmp1,"inner")Boundary(Region,Tmp1,"inner")Boundary(Region,Tmp1,"inner")Boundary(Region,Tmp1,"inner")boundary(Region,Tmp1,"inner")

union1(Tmp1,Tmp2)union1(Tmp1,Tmp2)Union1(Tmp1,Tmp2)Union1(Tmp1,Tmp2)Union1(Tmp1,Tmp2)union1(Tmp1,Tmp2)

skeleton(Tmp2,Result)skeleton(Tmp2,Result)Skeleton(Tmp2,Result)Skeleton(Tmp2,Result)Skeleton(Tmp2,Result)skeleton(Tmp2,Result)

'mixed'

In this mode the operator behaves like the mode 'medial_axis'"medial_axis""medial_axis""medial_axis""medial_axis""medial_axis" for non-overlapping regions. If regions touch or overlap, again separating lines between the input regions are generated on output, but this time including the “touching line” between regions, i.e., touching regions are separated by a line in the output region. This corresponds to the following calls:

Example：

erosion1(Region,Mask,Tmp1,1)erosion1(Region,Mask,Tmp1,1)Erosion1(Region,Mask,Tmp1,1)Erosion1(Region,Mask,Tmp1,1)Erosion1(Region,Mask,Tmp1,1)erosion1(Region,Mask,Tmp1,1)

union1(Tmp1,Tmp2)union1(Tmp1,Tmp2)Union1(Tmp1,Tmp2)Union1(Tmp1,Tmp2)Union1(Tmp1,Tmp2)union1(Tmp1,Tmp2)

complement(full,Tmp2,Tmp3)complement(full,Tmp2,Tmp3)Complement(full,Tmp2,Tmp3)Complement(full,Tmp2,Tmp3)Complement(full,Tmp2,Tmp3)complement(full,Tmp2,Tmp3)

skeleton(Tmp3,Result)skeleton(Tmp3,Result)Skeleton(Tmp3,Result)Skeleton(Tmp3,Result)Skeleton(Tmp3,Result)skeleton(Tmp3,Result)

where Mask denotes the following “cross mask”:
