(Appology in advance if I am asking a too nwbie question. I am a beginner with OpenCV. I have done some tutorials yet I have not a good grasp of it's concepts.)
Question: How to do head detection (not face detection) using OpenCV - For example in a photo of inside a bus or a room?
Note: I do not want to do face detection; just head detection to figure out number of people in the photo. Unfortunately - for me - those tutorials and documents that I'v found are about face detection and not head detection.
