我正在使用opencv的grabcut.cpp和graphcut.cpp代码调用函数grabcut()。我必须找到一种方法来保存从某些图像计算出的背景和前景模型,并将其应用到另一个图像。如何保存'bgdmodel'和'fgdmodel'以备将来使用?
这是我写的代码 -
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/imgproc/imgproc.hpp"
#include <iostream>
using namespace std;
using namespace cv;
int main()
{
// Load an image
Mat img = imread("1.png",1);
const Mat* img_0;
img_0= &img;
// Create the mask
Mat mask;
mask.create( img_0->size(), CV_8UC1);
mask.setTo( GC_BGD );
Mat bgdModel, fgdModel;
Rect rect;
rect.x=0;
rect.y=0;
rect.width=img.cols-1;
rect.height=img.rows-1;
(mask(rect)).setTo( Scalar(GC_BGD) );
grabCut(img, mask, rect, bgdModel, fgdModel, 1, GC_INIT_WITH_RECT);
// Save model to file
FileStorage fs("mymodels.xml", FileStorage::WRITE);
fs << "BgdModel" << bgdModel;
fs << "FgdModel" << fgdModel;
fs.release();
// Load another image
Mat img1 = imread( "abc.png", 1);
const Mat* img_1;
img_1= &img1;
// Load models from file
Mat bgdModel1, fgdModel1;
Mat mask1;
FileStorage fs1("mymodels.xml", FileStorage::READ);
fs1["BgdModel"] >> bgdModel1;
fs1["FgdModel"] >> fgdModel1;
fs1.release();
// Create a mask
mask1.create( img_1->size(), CV_8UC1);
mask1.setTo( GC_PR_FGD );
Rect rect1;
rect1.x=0;
rect1.y=0;
rect1.width=0;//img.cols;
rect1.height=0;//img.rows;
(mask1(rect1)).setTo( Scalar(GC_BGD) );
grabCut(img1, mask1, rect1, bgdModel1, fgdModel1, 1, GC_EVAL);
FileStorage fs2("finalmask.xml", FileStorage::WRITE);
fs2 << "Final_MASK" << mask1;
fs2.release();
for (int i=0;i<img1.rows;i++)
{
for(int j=0;j<img1.cols;j++)
{
if(mask1.at<uchar>(i,j)==0||mask1.at<uchar>(i,j)==2)
{
img1.at<cv::Vec3b>(i,j)[0] = 0;
img1.at<cv::Vec3b>(i,j)[1] = 0;
img1.at<cv::Vec3b>(i,j)[2] = 0;
}
}
}
imshow("Result of Grabcut", img1);
waitKey(0);
return 0;
}
我需要确保为imagex学习的bgdModel和fgdModel也适用于image1。

您可以使用<link rel="stylesheet" id="theme" href="" type="text/css">
保存背景和前景模型Mat
,然后将其重新加载以用于下一张图片。
这个例子应该澄清这一点:
