在OpenCV中进行图像叠加

void CPsView::ImgAdd(IplImage *inputImg,IplImage *inputImg1,IplImage *outputImg,double r)//图像叠加 { uchar *data= (uchar *)inputImg->imageData; int wp = inputImg->widthStep; uchar *data1= (uchar *)inputImg1->imageData; int wp1 = inputImg1->widthStep; uchar *data2= (uchar *)outputImg->imageData; int wp2 = outputImg->widthStep; for(int i = 0; i < inputImg->height; i++) { for(int j = 0; j < inputImg->width; j++) { data2[i * wp2 + 3 * j]=(1-r)*data[i * wp + 3 * j]+r*data1[i * wp1 + 3 * j]; data2[i * wp2 + 3 * j + 1]=(1-r)*data[i * wp + 3 * j + 1]+r*data1[i * wp1 + 3 * j + 1]; data2[i * wp2 + 3 * j + 2]=(1-r)*data[i * wp + 3 * j + 2]+r*data1[i * wp1 + 3 * j + 2]; } } } void CPsView::OnImgadd() { // TODO: Add your command handler code here CvvImage img1; img1.Load("E:\\新建文件夹\\sky.jpg"); IplImage * outputImg=cvCreateImage(cvSize(img1.Width(),img1.Height()), 8, 3); CPsDoc * pDoc = GetDocument(); ImgAdd(img1.GetImage(),pDoc->m_img.GetImage(),outputImg,0.3); cvSaveImage("E:\\新建文件夹\\add.jpg",outputImg); pDoc->m_img.Load("E:\\新建文件夹\\add.jpg"); Invalidate(); }
