MeasurementToImage

Replaces all labels of the input image by the result of an individual measurement.

Access to parameter description

For an introduction, see:

section Image Analysis
Analysis measurements

This algorithm replaces all labels of an input image by the result of an individual measurement. It supports the same individual measurements as any analysis algorithm (LabelAnalysis).
The data type of the output image depends on the selected measurement. It can be 32-bit floating point or integer.
For example, this algorithm can assign the surface value of a given object to all pixels that belong to it.
