gocv 这个库用法，求哥哥们指点

  WriteCloser · 1 天前 · 492 次点击

找了个 C 代码是这样写的，问题是这个库在 cv::compare的时候没有 这个 cv::GC_PR_FGD 我在库里面 cgo 调用时把它改为了 3 也是不行的。

有兄弟知道 gocv 怎么调用 grabCut 来抠图吗

cv::Mat image= cv::imread("../tower.jpg");
if (!image.data)
    {
    cout<<"不能打开图像！"<<endl;
    return 0; 
    }


cv::Rect rectangle(50,70,image.cols-150,image.rows-180);

cv::Mat result;
cv::Mat bgModel,fgModel; 
double tt = cv::getTickCount();
cv::grabCut(image,
    result,
    rectangle,
    bgModel,fgModel, 
    cv::GC_INIT_WITH_RECT); // 用矩形
tt = cv::getTickCount() - tt;
printf("算法执行执行时间:%g ms\n", tt/cv::getTickFrequency()*1000);

cv::compare(result,cv::GC_PR_FGD,result,cv::CMP_EQ);

cv::Mat foreground(image.size(),CV_8UC3,cv::Scalar(255,255,255));
image.copyTo(foreground,result);
