opencv实现图像邻域均值滤波、中值滤波、高斯滤波

 void CCVMFCView::OnBlurSmooth()//邻域均值滤波
 {
     IplImage* in;
     in = workImg;
     IplImage* out = cvCreateImage(cvGetSize(in),IPL_DEPTH_8U,workImg->nChannels);
     cvSmooth(in,out,CV_BLUR,3,workImg->nChannels);  //  简单平均
     m_dibFlag=imageReplace(out,&workImg);

     Invalidate();
 }

 void CCVMFCView::OnMedianSmooth()
 {
     IplImage* in = workImg;
     IplImage* out = cvCreateImage(cvGetSize(in),
         IPL_DEPTH_8U,workImg->nChannels);
     cvSmooth(in,out,CV_MEDIAN,3,workImg->nChannels);  //  中值滤波
     m_dibFlag=imageReplace(out,&workImg);

     Invalidate();
 }

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