Abstract(in English) The purpose of this report is to improve an instance-based deskewing technique which is free from the conventional assumption that text lines are straight and parallel. The instances describe the relation among the skew angle, a skew variant, and a skew invariant in an compact manner. A main idea of the improvement is to increase the number of the skew invariants for more stable estimation of the skew angle. An experimental result on 55 document images showed that their skew angles were successfully estimated with errors smaller than 2.0 degrees.
