As suggested, you can use the floodfill. For your image, this code will probably work out.
//Use this mouse call back for selecting the seedpoint.
void onMouse( int event, int x, int y, int, void* ) {
if( event != EVENT_LBUTTONDOWN )
return;
//Floodfill the image with green colour.
floodFill(InputImage, Point(x,y), Scalar(0,255,0), NULL, Scalar::all(10), Scalar::all(10));
imshow("FloodFill",InputImage);
}
