CakePHP OCR Scanning to find text in JPG, PNG, PDF

I need a cakePHP class with two functions that will return some values.

function scan_wageSlip( )

Will take as its input a scanned wage slip and return from the wage slip the following values ($GrossSalary, $NetSalary,

The wage slip documents are from many sources with no fixed format. The terms "Gross Salary" and "Net Salary" may have many variants (e.g. Net Salary, Net Pay, Net Wage, Net Wages, Net Payment) so a table of match strings is required to search for on the wage slip.


function scan_bankStatement( )
Will take a scanned bank statement as its input along with $NetPay.
It will return $BankDeposit, $DepositDescription, $exact as Boolean

You will need to identify the "Credits" column on the statement and search the column for the $NetPay figure or the nearest amount to it. $DepositDescription is the description on the bank statement for the row that the deposit came from and $exact is a Boolean to indicate whether $NetPay was matched exactly on the the bank statement or not.

I believe there are free OCR libraries available to help but I haven't looked into this in much detail.

The scope of this project is not to integrate this into my system, just develop this class and provide a test script so that I can validate the code using multiple
different wage slips and bank statements.

The test script should just browse for documents to upload and display on screen the values detailed above. This does not need to be pretty, just functional as it is for the purposes of validating your work only.
