Component list
The list of all components is made (all Paper componnets, not Ink!) and all their parameters are measured and registered. Those parameters include X and Y dimensions, X and Y center coordinates, number of selected pixels, and the Euclid`s distance from the center of the frame.

This is the hard task for MPU and it takes a lot of time to execute, almost 150 ms. All standard connected components algorithms use aditional buffers which take as much more RAM as the main frame buffer, so I had to develop my own algorithm for "poor man's" processing unit with limited data memory.
