示例1: removePinkCandidate
//Remove pink pocket from vector that is between 2 green points.
void PointLocator::removePinkCandidate(cv::vector<cv::KeyPoint> &pinkKeyPoints, cv::KeyPoint firstPocket, cv::KeyPoint secondPocket){
//First check that there are actually pink pocket points
if (!pinkKeyPoints.empty()){
float distance = -1;
int min = 0;
cv::KeyPoint middlePoint;
middlePoint.pt.x = (firstPocket.pt.x + secondPocket.pt.x) / 2;
