Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a method to detect partial duplications in an image. We treat a complex duplication accompanied with affine transformation. The proposed method improves the conventional method to estimate a transformation matrix of finely partial duplication by means of SIFT and RANSAC. Based on the estimation result, a duplicated region is detected in detail and is represented by different colors on an image. We have conducted experiments in the case of various transformations and confirmed the effectiveness of the proposed method.
