Abstract
The paper proposed a robust skew estimation method for the old printed document that estimates global and local skew angles. The global skew angle characterizes the main skew angle of the document image. In order to identify it, the longest object was extracted. Then, its skew was estimated with the moments. Accordingly, document image was globally de-skewed. The local skew angle represents a fine variation of each text line after deskewing document image. Creating vertical projection profiles of deskewed document identified different text lines. Line through text objects joined them in each text line. At the end, text skew of such objects was estimated by the moments identifying local text skews.
