I would like to detect squares in a limited field of a detected frame, such as the first 200 pixels. I see the squares example, and have a general idea that I might only process squares that in the far left by specifying some maximum x-cordinate. I'm wondering if there are any functions I can make use of, to do this, or how I might set limits on the frame to be interpreted.

OpenCV, and computer vision newbie here

Well, if you look in the Tutorials, the very first one has the example of how to refer to just a subsection of the matrix.

Most of your basic questions are answered there.
