HS / Homer123123:
I know image processing software but not the hardware.  I could easily
write some code to do what you asked but as to how to implement that
in hardware such as NAND gates, inverters, and comparators - I don't
know.  I suggest you talk to some company (or someone in your company)
who can design you a custom ASIC chip.  That custom chip can just suck
up your 30x30 matrix and spit out the number.
