24-3 動径基底補間法によるラプラシアン情報を用いた画像拡大

抄録

In this paper, Laplacian images are used in order to restore high frequency components required for digital image enlargement. Moreover, RBI method is applied to a sampled image and its Laplacian images for enlargement, and the Laplacian image is added to the enlarged sampled image. As a result, it is shown that the proposed method improves jaggy edges and restores high frequency components on enlarged images.
