Abstract (in Japanese) (See Japanese page) 
(in English) This study aims to develop a method of automatic interpolation for efficient anime production. The software has been commercially available, but they require the input order of pen strokes to be consistent among the drawings to specify the stroke correspondence. This requirement heavily loses usability in a production studio. We propose a method to estimate stroke correspondence using a graph matching algorithm. Through experiments, we confirmed that an appropriate estimation result was obtained with simple drawings had a small number of strokes using the proposed method.
