Abstract (in Japanese) (See Japanese page) 
(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.
