Algorithm to count people in a crowd

Question

We need to count the number of people in a crowd and we have used the opencv_traincascade but it detects many things.

What could be the other approach we can use?

I was looking for something like that. I have found this project HeadCounter ( https://github.com/yquemener/HeadCounter ) and some papers: "Counting in Extremely Dense Crowd Images" ( http://crcv.ucf.edu/projects/crowdCounting/index.php ) and "Crowd Size Estimation" ( http://course1.winona.edu/cmalone/promotion/UndergraduateResearch/Cariveau%20Report.pdf )
