我使用以下代码使用grabCut算法:
cv::Mat img=[self cvMatFromUIImage:image];
cv::Rect rectangle(10,10,300,150);
cv::Mat result; // segmentation (4 possible values)
cv::Mat bgModel,fgModel; // the models (internally used)
// GrabCut segmentation
cv::grabCut(img, // input image
result, // segmentation result
rectangle, // rectangle containing foreground
bgModel,fgModel, // models
3, // number of iterations
cv::GC_INIT_WITH_RECT); // use rectangle
// Get the pixels marked as likely foreground
cv::compare(result,cv::GC_PR_FGD,result,cv::CMP_EQ);
// Generate output image
cv::Mat foreground(img.size(),CV_8UC3,
cv::Scalar(255,255,255));
result=result&1;
img.copyTo(foreground, result);
result);
image=[self UIImageFromCVMat:foreground];
ImgView.image=image;
转换UIImage为的代码Mat image如下所示
