There is no easy and fast way to satisfy your requirements. For the beginning you can learn how to detect objects in OpenCV.

After this you can check haarcascade_fullbody.xml from OpenCV sources. This cascade is for detecting bodies, open it in text editor, there is additional information in header. Anyway, I'm not sure that existing cascade is too accurate for your needs.
