实验效果:
代码地址:https://github.com/cyssmile/openCV_learning_notes/blob/master/opencv_test/opencv_030/main.cpp
#include<opencv2/opencv.hpp>
#include<iostream>
using namespace std;
using namespace cv;
int main(int argc,char** arrgv)
{
Mat source = imread("D:/images/test.jpg",IMREAD_GRAYSCALE);
if (source.empty())
{
cout << "can`t open this ph" << endl;
}
imshow("source",source);
source.convertTo(source,CV_32FC1,1.0/255.0);
Mat sourceComplex[2] = {source,Mat::zeros(source.size(),CV_32F)};
Mat dftReady;
merge(sourceComplex, 2, dftReady);
dft(dftReady,dftReady,DFT_COMPLEX_OUTPUT);
Mat dst;
dft(dftReady, dst, DFT_INVERSE | DFT_REAL_OUTPUT | DFT_SCALE);
imshow("invertDft", dst);
waitKey(0);
destroyAllWindows();
return 0;
}
注意:如果在预处理阶段。没有进行尺度变换会出现以下结果:
source.convertTo(source,CV_32FC1,1.0);
正常应该
source.convertTo(source,CV_32FC1,1.0/255.0);
