| Abstract(in English) | A novel deformation estimation technique is proposed and applied to document skew estimation. The proposed method has two properties. First, it utilizes an invariant and a variant of a target deformation to be estimated. Second, it is an instance-based method where the deformation is estimated by referring stored instances which describe the relation among the deformation, the variant, and the invariant. The result of a skew estimation experiment on 44 document images has shown that the skew angles of 42 document images were successfully estimated with errors smaller than 2.0 degrees. |
