opencv实现图像邻域均值滤波、中值滤波、高斯滤波

[cpp] view plain copy

 

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();
}
