如果您已经有了要替换的点或什至更好的轮廓(例如第二张图中以绿色绘制的轮廓)，请查看inpaint : http://docs.opencv.org/3.1.0/d1/d0d/group__photo.html#gaedd30dfa0214fec4c88138b51d678085

If you already have the points or even better contours you want to replace (like these drawn in green in your 2nd image), have a look at inpaint: http://docs.opencv.org/3.1.0/d1/d0d/group__photo.html#gaedd30dfa0214fec4c88138b51d678085

我认为这正是您要寻找的！参见此处的示例: https://en.wikipedia.org/wiki/Inpainting

I think this is exactly what you are looking for! See here for an example: https://en.wikipedia.org/wiki/Inpainting

过程非常简单:

1. 制作一个填充有轮廓( drawContours ，厚度: CV_FILLED )的蒙版，以对其各自的环境进行修补/替换.
2. inpaint (带有此蒙版).

1. Make a mask filled with your contours (drawContours, thickness: CV_FILLED) to be inpainted/replaced with their respective environment and
2. inpaint with this mask.

我应该提到，这仅适用于8bit图像.

I should mention that this does only work with 8bit-images.

下面的(未经测试的)代码段应该可以实现.

The following (untested) code snippet should do it.

Mat mask = Mat::zeros(img.size(), CV_8UC1);
for (int i = 0; i < contours.size(); i++)
  drawContours(mask, contours, i, Scalar::all(255), CV_FILLED);
Mat dst;
double radius = 20;    
inpaint(img, mask, dst, radius, INPAINT_NS);
//inpaint(img, mask, dst, radius, INPAINT_TELEA);
imshow("dst", dst);
waitKey();

要绘制几个点的轮廓，请执行以下操作:轮廓只是点的向量，打包成另一个向量.因此，对于给定的 vector< Point&gt ;，解决方案应该是这样的.点.

To make a contour of a couple of points: A contour is just a vector of points, packed into another vector. So, the solution should be something like this with a given vector<Point> points.

vector<vector<Point> > contours;
contours.push_back(points);
drawContours(mask, contours, 0, Scalar::all(255), CV_FILLED);
