Purpose

The module ComplexToReal computes either the absolute, power, phase, real- or imaginary part of complex numbers in an image.

Usage

Select the function you want to apply to the input image.

Windows

Default Panel

Input Fields

input0

name: input0, type: Image

The input image can be of any type.

If the input is not of complex type, it is automatically cast to complex double.

Output Fields

output0

name: output0, type: Image

The output image containg real numbers.

Parameter Fields

Visible Fields

Operators

name: Operators, type: Enum, default: Absolute

Selects the mode how complex input voxels are converted to the scalar output voxels.

Values:

Title	Name	Description
Absolute	Absolute	The absolute of the value of each voxel is computed.
Argument	Argument	The argument or phase of the value of each voxel is computed.
Power	Power	The power spectrum of the value of each voxel is computed.
Real	Real	The real part of the value of each voxel is computed.
Imaginary	Imaginary	The imaginary part of the value of each voxel is computed.
