VS 2010 Optical Character Recognition - Grabbing words form the entire screen ( EMGU )

Hello there fellow developers,

here I am again several years later, face-palming at my previous thread..

Anyway my question this time is; Grabbing keywords from the screen using EMGU OCR libraries.

Here's the story: My current application requires longitude and latitude data from a certain video game to determine the location of the player. The game client is secured against memory reading and such, so I went with OCR ( and also because packet sniffing and such is still pretty much witchcraft to me, yes it's an MMO ) to get this information. Now, the application has a separate form, let's call it the 'locator', that is placed over the radar to read the Lon and Lat text, which it then converts into usable data.

The problem is ( not really a problem, it's more of an inconvenience ) that the user has to place the locator over the radar manually, which not only takes a few seconds but the overall look isn't very professional. That is why I would like to have the OCR find the lon&lat text in a screenshot of the whole entire screen and deal with that. Not only would it make the application more user friendly and compact ( having one less form to deal with ) but also more efficient by eliminating the human error factor as the user can misplace the locator, which might result in the OCR not reading the text correctly.

So my question to you is, how would one go about achieving this? I know it is possible as I know a similar application to mine for the same exact game that does just that.

The only thing I could think of so far, is having the OCR read the whole screen and pray it finds the Lon & Lat keywords. But before I try this I want your input, just in case this idea is ludicrous.

Here's a video of one of the scripts in action.
