hI,
This is my first post.
I am working on image processing. I am storing a video frame thru a frame grabber & i want to compare that image with some standard sto get that the video is perfect.

can anybody tell me how to compare this ,the important thing is i don't want to use a COMPUTER , so can i program any microcontroller for this or is there any other way to it. :cry:

PLZ SUGGEST SOMETHING as this is my first project & I am an COMPUTER ENGG.

You could do this with a 8bit microcontroller but it would be slow: on the order of a second probably. You should definately use one with an external memory bus. If you need it to be faster a CPLD (a programmable logic device) might be a good choice. You can fetch from memory, test the tolerance and output a result without too much logic.
