opencv实现图像邻域均值滤波、中值滤波、高斯滤波

1. void CCVMFCView::OnBlurSmooth()//邻域均值滤波
2. {
3. IplImage* in;
4. in = workImg;
5. IplImage* out = cvCreateImage(cvGetSize(in),IPL_DEPTH_8U,workImg->nChannels);
6. cvSmooth(in,out,CV_BLUR,3,workImg->nChannels);  //  简单平均
7. m_dibFlag=imageReplace(out,&workImg);
8. Invalidate();
9. }

1. void CCVMFCView::OnMedianSmooth()
2. {
3. IplImage* in = workImg;
4. IplImage* out = cvCreateImage(cvGetSize(in),
5. IPL_DEPTH_8U,workImg->nChannels);
6. cvSmooth(in,out,CV_MEDIAN,3,workImg->nChannels);  //  中值滤波
7. m_dibFlag=imageReplace(out,&workImg);
8. Invalidate();
9. }

1. void CCVMFCView::OnGaussSmooth()
2. {
3. IplImage* in = workImg;
4. IplImage* out = cvCreateImage(cvGetSize(in),IPL_DEPTH_8U,workImg->nChannels);   //  建立辅助位图
5. cvSmooth(in,out,CV_GAUSSIAN,3,workImg->nChannels);  //  Gauss 平滑
6. m_dibFlag=imageReplace(out,&workImg);   //  输出处理结果
7. Invalidate();
8. }
