Module: Opening / Maximal Linear Opening ()
Maximal Linear Opening is one of the configurations of the module Opening. For other configurations, see the port Type.
For an introduction, see:
This module performs the union of the openings in several directions (binary case) or the maximum of the openings (grayscale case). This module is very useful when you work with circular shapes because it fills the holes in all directions. Like a classical opening transform, using this module with an appropriate threshold allows getting a Top Hat well adapted to the circular object detection.

Input Image [required]
The input image to be processed. Supported types include: binary and label image (Uniform Label Field), grayscale image (Uniform Scalar Field) and color image (Uniform Color Field).
Type
This port selects the configuration of this module. The available configurations are:Interpretation
This port specifies whether the input will be interpreted as a 3D volume or a stack of 2D images for processing.
- "3D": the module configuration is set to 3D. The image will be processed as a whole in 3D.
- "XY planes": the module configuration is set to 2D. The image will be processed slice per slice.
Size
This port refers to the half-kernel size.Number Of Angles
This port refers to the number of samples used around unit circle (or unit sphere in 3D).
