An Accurate IFS-based Image Enlargement Method using Edge Continuity

Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes an effective image enlargement method based on an Iterated Function System(IFS). The proposed method introduces a line process into the IFS-based enlargement procedures to solve edge discontinuity of an enlarged image in the traditional IFS schemes. The line process can detect the edges which retain continuity. However, the line process cannot apply to the enlarged image whose intensities are not known. Therefore, the proposed method estimates the enlarged image's edges from the target image's edges obtained by using the line process. Then, since the estimated edges retain the continuity, the proposed method can calculate the enlarged image in such a way that its edges retain the continuity. Consequently, an accurate image enlargement can be achieved.
