Hi Doug,
You should be able to use a global variable to pass data from your Vision Processing VI to the other parts of your code. You can pass values individually, but if multiple values will always be used in the same places in your code (such as x & y coordinates, and perhaps color values) then you can bundle these values together into a cluster. You can create a global variable that is defined as a cluster of the same data types, and then pass your bundled data to that global variable in the Vision Processing VI, and read out the cluster anywhere else you need to in your code.
Be careful using global variables though. While they are necessary in some situations like this, you should always pass data by wire if you are able. It's faster and makes your code easier to understand. Additionally, introducing global variables also introduces the possibilities for race conditions in your code. To avoid this pitfall, always make sure that you are only writing to your global variable in once place, though you can read from it in many locations. If you do need to update a global variable from multiple locations, you need to protect that section of code to ensure that the global variable can only be updated in a single location at any given time.
For more information on the use of local, global variables, and functional global variables, see these resources:

The LabVIEW Help also has some good information on creating and using variables.
Good Luck, and let me know if you have further questions!
