delphi OCR component

I need either a Delphi 5 component or just the actual delphi code to do the following: To interpret the last spins of the roulette wheel on various online casinos and to present the data back into the program as integer/numeric rather than the image which appears on the web site. most (if not all) roulette games will display the last spins in a column of numbers, so the program just needs to determine when this column of numbers (images) change, and to report back to the software what the last number was that was spun! The code needs to be 100% accurate as to the numbers that are displayed/returned, and should only need to recognise the numbers 0 through to 36 (standard roulette numbers). Because every website will have different fonts/sizes/position, then the code will need to be able to firstly select the region/area to scan for the numbers to appear in, and then monitor that area/region and report back the last number(s) that are spun. This means that the code will have to check the last column of numbers every nn seconds to check if they have changed (user defined number of seconds). Final deliverable will either be source code that I can add to myself in Delphi V5, or a VCL component that I can add into Delphi V5 and retain the source code for.
