| Digitalization is a process of converting content of legacy media to a digital, computer-accessible form. Digitalization of text is currently well-established, supported by OCR-related image processing techniques. Digitalization of tabular text data, which are common in business and accounting systems, is problematic for a simple OCR algorithm that does not concern the placement or relations of table cells.
The goal of this thesis is to implement a user-friendly software capable of converting image data to tabular form. Resulting software should be able to surpass common deficiencies in scanner-generated input, and output an intermediate textual representation of the page as a tabular data (including e.g. sub-tables, margins, colors, or non-tabular text or image elements), which can be easily converted to e.g. CSV, XLS or TeX format. |
