This paper presents a methodology for automated data entry of salary payslips from document images. The challenging problems are 1) the payslips vary from one company to another, and 2) the appeared wording terms are different but similar meaning terms. The proposed methodology is the essential preprocess by using image processing and regular expression setting before an optical character recognition or OCR. The post-process for number validation must be considered by checking the financial formula.
