phase_radphase_radPhaseRadPhaseRadphase_rad (Operator)
Name
phase_radphase_radPhaseRadPhaseRadphase_rad — Return the phase of a complex image in radians.
Signature
Description
phase_radphase_radPhaseRadPhaseRadphase_rad computes the phase of a complex image in
radians. The following formula is used:
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.
- Automatically parallelized on channel level.
- Automatically parallelized on domain level.
Parameters
ImageComplexImageComplexImageCompleximageCompleximage_complex (input_object) (multichannel-)image(-array) → objectHImageHObjectHObjectHobject (complex)
Input image in frequency domain.
ImagePhaseImagePhaseImagePhaseimagePhaseimage_phase (output_object) image(-array) → objectHImageHObjectHObjectHobject * (real)
Phase of the image in radians.
Example (C)
read_image(&Image,"monkey");
disp_image(Image,WindowHandle);
fft_image(Image,&FFT);
phase_rad(FFT,&Phase);
disp_image(Phase,WindowHandle);
Result
phase_radphase_radPhaseRadPhaseRadphase_rad returns 2 (
H_MSG_TRUE)
if the image is of correct
type. If the input is empty the behavior can be set via
set_system(::'no_object_result',<Result>:)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>).
If necessary, an exception is raised.
