Detailed Description

Union of openings calculated for several linear structuring element orientations on 3d images.

The 3d union linear opening algorithm computes openings in several directions with linear structuring elements and combines them to keep the maximum pixel intensity. The structuring element orientations vary in order to describe a regular grid on a 3d sphere (see the IPSDKCore documentation, section IPSDK concepts > Notations and conventions). This algorithm is usefull to fill circular light holes inside dark objects while preserving thin light structures.

Just like Union linear opening 2d, the algorithm can handle holes to avoid contact with the image border. See the Opening 2d description for more details.

By default, the algorithm uses 6 different regularly distributed angles with the math::computeUniformlyDistOrientations3d(nbAngles) function.

See Union linear opening 2d for an illustration of the union linear closing in two dimensions.
