phase_radphase_radPhaseRadPhaseRadphase_rad (算子名称)

名称

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

参数签名

phase_rad(ImageComplex : ImagePhase : : )

描述

phase_radphase_radPhaseRadPhaseRadPhaseRadphase_rad computes the phase of a complex image in radians. The following formula is used: phase = atan2(imaginary part,real part) .

运行信息

多线程类型:可重入(与非独占操作符并行运行)。
多线程作用域:全局(可以从任何线程调用)。
在元组级别自动并行化。
在图像通道级别自动并行化。
Automatically parallelized on domain level.

参数表

ImageComplexImageComplexImageComplexImageCompleximageCompleximage_complex (input_object) (multichannel-)image(-array) → object (complex)

Input image in frequency domain.

ImagePhaseImagePhaseImagePhaseImagePhaseimagePhaseimage_phase (output_object) image(-array) → object (real)

Phase of the image in radians.

例程 (C)

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

结果

phase_radphase_radPhaseRadPhaseRadPhaseRadphase_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>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>). 如有必要，将引发异常。
