Abstract A novel document skew (i.e., rotation) estimation technique proposed in this paper has two properties: First, it estimates the rotation angle at each connected component. The entire rotation angle is determined by voting all the estimated rotation angles. Second, it employs instance-based learning where the rotation angle is estimated by referring stored instances each of which consists of a rotation invariant and a rotation variant. The result of a skew estimation experiment on 55 document images has shown that the skew angles of 54 document images were successfully estimated with errors smaller than 2.0 degrees.
