Module: Pore_Merge

Description:

Given a set of pores (or elements in general), with each non-zero value identifying a distinct object, if such an object has a high enough amount of its surface in contact with other objects (i.e. not counting the interface with zero-valued pixels), then it will be merged to the object with which it shares the most. Applied until convergence.

Illustration on a set of six pores. On the left, a poor decomposition: the red and purple pores share 63% and 54% respectively with their blue neighbour. On the right is the result of the merging.

Connections:

[required]
The input image comes in through this port. For now, the only input type that has been implemented is HxUniformScalarField3.

Ports:

Do

Push the button to open the input.

Ratio

Ratio of the connecting surfaces to the total surface.

Commands:

Additional options can be accessed when typing in the console Pore_Merge COMMAND_NAME. Typing the command again usually reverts back to original settings.

`verbose`

Displays timing information after the computation. Retype to hide info.

`create`

Runs the computation. Returns the name of the output, so it can be used in a script, such as set RESULT [Pore_Merge create].

`debug`

Turns on or off debug mode, giving info on which pores are checked, how much surface they share with their neighbours, etc.
