phase_radphase_radphase_radPhaseRadPhaseRad (Operator)

Name

phase_radphase_radphase_radPhaseRadPhaseRad — Return the phase of a complex image in radians.

Signature

Description

phase_radphase_radphase_radPhaseRadPhaseRad computes the phase of a complex image in radians. The following formula is used:

  phase = atan2(imaginary part,real part) .

Parallelization

• 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 domain level.

Parameters

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