Module: Gradient_Metrify

Description:

Transforms a gradient (see Gradient or Deriche) into a metric with the formula

. Used for segmentation purposes (e.g. Continuous Maximal Flow).

From left to right: Original image, gradient, and metric.

Connections:

Image

[required]
From this port, the input gradient is retrieved. The input type must be HxUniformScalarField3.

Ports:

Normalisation

Normalisation factor, or soft significance threshold. The N in the formula.

P

Power to which gradient is raised (1 or 2). The p in the formula.

Epsilon

Surface area penalty coefficient. The ε in the formula.

HAYAAAAI

Pressing this button starts the computation.

Commands:

Additional options can be accessed when typing in the console Gradient_Metrify 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 [Gradient_Metrify create].
