To "recognize" people may be a bit difficult. If you just want to
count the people entering a bus door, typically you use an
photoelectric sensror (for door/gate/elevator use). They
are very easy to be interfaced with any MCU, including
an AVR.

More established vendors:
Pepperl+Fuchs, SICK, Omron, SUNX, Banner Engineering
and many others.
