KillBorder3d

Removes the objects connected to the borders of a segmented image.

Access to parameter description

For an introduction: This algorithm removes all the objects touching the borders of the 3D image.
Objects connected to the label image borders are identified using a numerical reconstruction from markers made of pixels of the image frame. Then we remove these objects from the input image with a logical subtraction.

To reorder labels use ReorderLabels algorithm

Parameters

Parameter Name Description Type Supported Values Default Value
input
inputObjectImage
The input binary or label image. Image Binary or Label nullptr
input
neighborhood
The 3D neighborhood configuration.
CONNECTIVITY_6 The structuring element is composed of voxels with a common face with the voxel of interest.
CONNECTIVITY_18 The structuring element is composed of voxels with at least one common edge.
CONNECTIVITY_26 The structuring element is a full cube.
Enumeration CONNECTIVITY_26
output

Object Examples

auto foam_sep = readVipImage( std::string( IMAGEDEVDATA_IMAGES_FOLDER ) + "foam_sep.vip" );

KillBorder3d killBorder3dAlgo;
killBorder3dAlgo.setInputObjectImage( foam_sep );
killBorder3dAlgo.setNeighborhood( KillBorder3d::Neighborhood::CONNECTIVITY_26 );
killBorder3dAlgo.execute();

std::cout << "outputObjectImage:" << killBorder3dAlgo.outputObjectImage()->toString();

Function Examples

auto foam_sep = readVipImage( std::string( IMAGEDEVDATA_IMAGES_FOLDER ) + "foam_sep.vip" );

auto result = killBorder3d( foam_sep, KillBorder3d::Neighborhood::CONNECTIVITY_26 );

std::cout << "outputObjectImage:" << result->toString();
