OpenCV: Detect people in city square
===

I need to find all people or group of people in city square like this. I use `CascadeClassifier.detectMultiScale` function and prepare image by `equalizeHist` (correct brightness and contrast)![enter image description here][1]

As you can see not all people was found. 

In description to `haarcascade_fullbody.xml` i read that detector support only frontal and back views. 

Do you know some haarcascades collection for this problem, or may be i need to correct my code and leave this cascades?
