Comparison between initial skew rate and moment based method for the printed text skew estimation

In this paper, the methods for the estimation of the printed text skew are explored. Initail skew rate and moment based method are presented. They are tested with single and multi line document image samples in different resolutions. Furthermore, the results are evaluated by common measures. Moment based method proved its advantage in the domain of accuracy and robustness over the initial skew rate method.
