   [ C++ ]  Taking screenshot from webcam every .1 seconds
  Thanks for the help in advance. The program must take the image from a webcam (I can go with any webcam). Get the pixels to determine if the qualifications of the image are met. Every .1 seconds.  If you know how to do this that would be very helpful!   
  Depends on the operating system you have to use. On windows you're gonna gave to use some kind of video libraries and driver interfaces, on unix-like systems you'd simply read a sequence of JPEGs from a virtual file in /dev/video.   ;  This sounds like homework... This link shows how to capture images from a webcam, but you're going to need to write some code yourself. Linky to CodeProjectToolmaker   ;  I've been curious about how you went about doing that, but never to the point of actually looking it up. Thanks for the link.
