Methods for detection of helmet on a motorcyclist.

Hello,

I require help in choosing an appropriate method to detect the presence of a helmet on a motorcyclist, I am using a live camera feed and use of computer vision toolbox, please suggest methods which can be quick enough to distinguish between "helmet" and "no helmet".

Using: MATLAB R2015a

Thank you for your help.
