Simulink Block Processing - internal start-of-frame indicator?

Hi,
I'm using the Simulink block processing object for some computer vision work. I feed it frames (from a video), it splits those frames into small blocks that I can work on, and then it reassembles the frame afterwards.
However, I've found that I really need a "start of frame" (or "end of frame") indicator for the things that happen inside. For example, there's a block that averages the entire image by adding up all the blocks, and it obviously needs to know when one frame finishes and the next one starts. I know that it'd be much easier to do the averaging outside the block processing object, but that's not practical when it's implemented in hardware (because I don't get a whole frame at a time, I get a stream of pixels).
Is there some way to achieve this, or do I have to implement a counter inside that counts how many pixels have been provided and outputs a frame-sync signal after a full image has been transferred?
Cheers, Evan
