phase_degphase_degPhaseDegPhaseDegphase_deg (Operator)

Name

phase_degphase_degPhaseDegPhaseDegphase_deg — Return the phase of a complex image in degrees.

Signature

Description

phase_degphase_degPhaseDegPhaseDegPhaseDegphase_deg computes the phase of a complex image in degrees. The following formula is used: Hence, ImagePhaseImagePhaseImagePhaseImagePhaseimagePhaseimage_phase contains half the phase angle. For negative phase angles, 180 is added.

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

Example (C)

read_image(&Image,"monkey");
disp_image(Image,WindowHandle);
fft_image(Image,&FFT);
phase_deg(FFT,&Phase);
disp_image(Phase,WindowHandle);

Result

phase_degphase_degPhaseDegPhaseDegPhaseDegphase_deg 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>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>). If necessary, an exception is raised.
