Cell decomposition for the table in document image based on analysis of texts and lines distribution

This paper proposes a method to extract table cells from document images. In standard cases, we can extract the cells using the ruling lines. But, there are also cases where the ruling lines are omitted. In such cases, the existing lines, if any, and the distribution of text blocks is the only information to decompose the table. In our method, the input image is divided into text and lines images. And then, we decompose the table from those two images separately. Finally, we analyze the cells obtained from the previous step and decide the final result of the table decomposition.
