convol_gaborconvol_gaborConvolGaborConvolGaborconvol_gabor — 在频域中用伽柏滤波器对图像进行卷积。

签名

convol_gabor(ImageFFT, GaborFilter : ImageResultGabor, ImageResultHilbert : : )

描述

convol_gaborconvol_gaborConvolGaborConvolGaborConvolGaborconvol_gabor convolves a Fourier-transformed image with a Gabor filter GaborFilterGaborFilterGaborFilterGaborFiltergaborFiltergabor_filter (see gen_gaborgen_gaborGenGaborGenGaborGenGaborgen_gabor) and its Hilbert transform in the frequency domain. The result image is of type 'complex'"complex""complex""complex""complex""complex".

注意

The filtering is always done on the entire image, i.e., the domain of the image is ignored.

执行信息

多线程类型：可重入（与非独占算子并行运行）。
多线程作用域：全局（可从任何线程调用）。
在元组级别上自动并行化。
在通道级别上自动并行化。

示例（HDevelop）

gen_gabor(Filter,1.4,0.4,1.0,1.5,'n','dc_edge',512,512)
fft_generic(Image,ImageFFT,'to_freq',-1,'none','dc_edge','complex')
convol_gabor(ImageFFT,Filter,Gabor,Hilbert)
fft_generic(Gabor,GaborInv,'from_freq',1,'none','dc_edge','byte')
fft_generic(Hilbert,HilbertInv,'from_freq',1,'none','dc_edge','byte')
energy_gabor(GaborInv,HilbertInv,Energy)

结果

convol_gaborconvol_gaborConvolGaborConvolGaborConvolGaborconvol_gabor returns 2 ( H_MSG_TRUE) if all images are of correct type.当输入为空时，可设置行为通过算子 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，则抛出异常。
