问题描述
我想写一个维纳滤镜来改善图像。我不想使用傅里叶变换,我知道有一个中值和方差为基础的ALG,但我找不到它。你能帮助我吗?我想这就是你要找的。a>这段代码是由Ray Juang编写的。
使用上面的代码的例子
pre $ void $(main argc, char * argv [])
if(argc printf(Usage:%s< image> \\\
,argv [0]);
return;
}
IplImage * tmp = cvLoadImage(argv [1]);
IplImage * tmp2 = cvCreateImage(cvSize(tmp-> width,tmp-> height),IPL_DEPTH_8U,1);
cvCvtColor(tmp,tmp2,CV_RGB2GRAY);
cvNamedWindow(Before);
cvShowImage(Before,tmp);
cvWiener2(tmp2,tmp2,3,3);
cvNamedWindow(After);
cvShowImage(After,tmp2);
//cvSaveImage(\"C:/temp/result.png,tmp2);
cvWaitKey(-1);
cvReleaseImage(& tmp);
cvReleaseImage(& tmp2);
}
I want to write a Wiener filter to improve an image. I don't want to use fourier, i know there is a median and variance based alg, but i can't find it. Can you help me guys?http://en.wikipedia.org/wiki/Wiener_filter
I think this is what you are looking for. This code is written by Ray Juang.
example on using above code
void main(int argc, char *argv[])
if (argc <= 1) {
printf("Usage: %s <image>\n", argv[0]);
return;
}
IplImage *tmp = cvLoadImage(argv[1]);
IplImage *tmp2 = cvCreateImage(cvSize(tmp->width, tmp->height), IPL_DEPTH_8U, 1);
cvCvtColor(tmp, tmp2, CV_RGB2GRAY);
cvNamedWindow("Before");
cvShowImage("Before", tmp);
cvWiener2(tmp2, tmp2, 3,3);
cvNamedWindow("After");
cvShowImage("After", tmp2);
//cvSaveImage("C:/temp/result.png", tmp2);
cvWaitKey(-1);
cvReleaseImage(&tmp);
cvReleaseImage(&tmp2);
}
