Robust Skew Estimation on Low-Resolution Document Images
In this paper, we present a new technique for estimating an arbitrary skew angle using a simple and efficient text row accumulation based on the statistics of the 1st and 2nd orders. In contrast to other works, where an image resolution of 100-300 dpi is necessary, a lower resolution (50 dpi) is enough for our method to obtain a correct result. The performance of the method was evaluated on the database UW -I of the University of Washington and compared with one advanced Hough transform-based method. A significantly lower error rate for our method confirms its advantages and benefits for automated document processing.
